D. Eigenvalue Problem of the Transformed Hamiltonian and the Parent Relations... 

This implies an essential simplification of the entire eigenvalue problem, since it will now be sufficient to consider only one of the two parent relations in Eq. (2.49), for instance... 

It is evident that if we are interested in physical resonances associated with complex eigenvalues of the transformed Hamiltonian H — UHU we have to avoid the trivial choices of bases. It follows directly from the so-called parent relations, Eq. (2.49), that if we like to relate the eigenvalue problem of... 

Prefixes and Affixes. Prefixes are arranged alphabetically and placed before the parent name multiplying affixes, if necessary, are inserted and do not alter the alphabetical order already attained. The parent name includes any syllables denoting a change of ring member or relating to the structure of a carbon chain. Nondetachable parts of parent names include... 

Daughter ion. An electrically charged product of a reaction of a particular parent ion. In general, such ions have a direct relationship to a particular precursor ion and, indeed, may relate to a... 

The common method of naming aldehydes corresponds very closely to that of the related acids (see Carboxylic acids), in that the term aldehyde is added to the base name of the acid. For example, formaldehyde (qv) comes from formic acid, acetaldehyde (qv) from acetic acid, and butyraldehyde (qv) from butyric acid. If the compound contains more than two aldehyde groups, or is cycHc, the name is formed using carbaldehyde to indicate the functionaUty. The lUPAC system of aldehyde nomenclature drops the final e from the name of the parent acycHc hydrocarbon and adds al If two aldehyde functional groups are present, the suffix -dialis used. The prefix formjlis used with polyfunctional compounds. Examples of nomenclature types are shown in Table 1. 

Within each chondrite class there are petrographic grades that relate to alteration processes that occurred within the meteorite parent body. The... 

Polymer Composition. The piopeities of foamed plastics aie influenced both by the foam stmctuie and, to a gieatei extent, by the piopeities of the parent polymer. The polymer phase description must include the additives present in that phase as well. The condition or state of the polymer phase (orientation, crystallinity, previous thermal history), as well as its chemical composition, determines the properties of that phase. The polymer state and cell geometry are intimately related because they are determined by common forces exerted during the expansion and stabilization of the foam. 

Tensile Strength and Elongation. The tensile strength of latex mbber foam has been shown to depend on the density of the foam (149,177) and on the tensile strength of the parent mbber (177,178). At low densities the tensile modulus approximates a linear relation with density but kicreases with a higher power of density at higher densities. Similar relations hold for polyurethane and other flexible foams (156,179,180). 

Hydroxyapatite, Ca2Q(PO (OH)2, may be regarded as the parent member of a whole series of stmcturaHy related calcium phosphates that can be represented by the formula M2q(ZO X2, where M is a metal or H O" Z is P, As, Si, Ga, S, or Cr and X is OH, F, Cl, Br, 1/2 CO, etc. The apatite compounds all exhibit the same type of hexagonal crystal stmcture. Included are a series of naturally occurring minerals, synthetic salts, and precipitated hydroxyapatites. Highly substituted apatites such as FrancoHte, Ca2Q(PO (C02) (F,0H)2, are the principal component of phosphate rock used for the production of both wet-process and furnace-process phosphoric acid. 

When sulfonic acids are neutralized to sulfonic acid salts, the materials become relatively innocuous and low in toxicity, as compared to the parent sulfonic acid (see Table 4). The neutralized materials cause considerably less eye and skin irritation. The most toxic route of entry for sulfonic acid salts is ingestion (39). The toxicity of neutralized sulfonic acids, especially detergent sulfonates, has been directiy related to the foaming capabiUty of the material. 

The requirements of a developer moiety for incorporation into a dye developer are well fulfilled by hydroquinones. Under neutral or acidic conditions hydroquinones are very weak reducing agents and the weakly acidic phenoHc groups confer tittle solubility. In alkali, however, hydroquinones are readily soluble, powerful developing agents. Dye developers containing hydroquinone moieties have solubility and redox characteristics in alkali related to those of the parent compounds. 

The NMR spectra of the parent compounds of the pyrido-[2,3-d]- and -[3,4- f]-pyridazine systems have been studied, together with those of some closely related derivatives parent compound, 282). In the pyrido[4,3-c]pyridazine series, only the spectrum of the dihydro compound (302) has been recorded <79X2027). 

In the [3,2-c ] series the spectra of the parent compound and some closely related analogues have been compared with those predicted from MO calculations of electron densities. The results confirm the predicted occiurence of a considerable degree of bond localization in these compounds <80KGS54l), as was previously found in their deaza (cinnoline) analogues <67JCS(B)1243). Other comparisons of NMR values with those expected from MO calculations for a series of azanaphthalenes have included some results with pyridopyridazines <75MI21500). 

V-Benzoylation of a 1,2,3,4-tetrahydro derivative is reported, whilst related 1,4-dialkyl derivatives resulted from borohydride reduction of the parent [2,3-f ] compound in the presence of carboxylic acids (79JHC973). 

Comparison with Eq. (4-20) provides an example of the parallelism that exists between the eqnaOons for a constant-composition sohiOon and those for the corresponding partial properties. This parallelism exists whenever the sohidon properties in the parent equation are related hnearly (in the algebraic sense). Thus, in view of Eqs. (4-17), (4-18), and (4-19) ...
