Peak range

Wampler and Jamieson (1980) studied 12 species of luminous earthworms belonging to six genera (Diplocardia, Diplotrema, Fletcherodrilus, Octochaetus, Pontodrilus and Spenceriella) from the United States, Australia and New Zealand, and found that all of the species exude luminous coelomic fluid from their dorsal pores, except Pontodrilus bermudensis that exudes the fluid from the mouth. All of them emit luminescence of broad emission spectra with the peaks ranging from 500 nm to over 570 nm. [Pg.235]

A reactor was charged with acrylic acid (20 g), 2-ethylhexyl acrylate (380 g), boiling point Spirit 69/95 (133 g), and 133 g of acetone. The mixture was then heated to 58°C and treated with Vazo-67 (0.2 g) and then further heated to 77°C. After a reaction time of 2.5 hours additional acetone (100 g) was added. After 4 hours the mixture was treated with additional Vazo-67 (0.2 g). After a further polymerization time of5 hours a second dilution with acetone (100 g) was made. Finally after an additional 6 hours the mixture was diluted with boiling point Spirit 60/95 (100 g). The polymerization was discontinued after 24 hours and the reaction vessel cooled to ambient temperature. The product was isolated having an Mw of 365,000 Da with a PDI of 16.46 with gas-phase chromatography (GPC) peaks ranging from 79,400 to 697,000 Da. [Pg.65]

In octahedral compounds such as Co[B(pz)j2 or [B(pz)4Mo(CO)j] the fourth, uncoordinated pz group maintains its separate NMR identity. This can be seen particularly well in the Co(II) complex, where the peaks range from —5500 to -t-6960 Hz (at 60 MHz) because of contact shifts. The fact that the pz groups show up as a 3 1 pattern implies a low barrier to rotation of the uncoordinated pz moiety about the B—N bond, thus making the environments of all 5-protons averaged. [Pg.28]

The Ca-Na and Na-Na g(r) have sharp peaks at about 4.0-4.5 A which is their average interatomic distance. The Ca-Ca g(r) shows a series of broader peaks ranging from 7.5 to about 15 A. This trend, which can be observed also in the gCa-Na tail, evidences that the Ca ions move in a more dense environment than the Na ions do, i.e. tlie inner part of the PGA network. [Pg.923]

These two fractions, designated as enzyme I and enzyme II, were subjected to isoelectric focusing, and each gave at least four active peaks. Enzyme I yielded fractions with isoelectric peaks ranging from pH 4.8 to 5.2, and enzyme II gave four fractions with peaks ranging from 4.05 to 4.60. [Pg.60]

The absorption peaks ranged from 499 nm for hexafluoroisopropanol (a very strong HBD solvent with high a) to 704 nm for hexamethylphosphoric acid triamide (a very strong EPD solvent with high /S). [Pg.390]

The recorded He(I) and He(II) photoelectron spectra of phenol contain several peaks ranging from 8.56 to 22.67 eV. It appears that the reported value of 8.56 eV is actually the first phenol vertical IE whereas that of 8.47 eV corresponds to its first adiabatic lEj. Geometry relaxation of the vertical ion results in a small stabilization. For comparison, note that the lEj(phenol) is computed to be 8.37 and 8.42 eV using B3LYP and CCSD(T), respectively, in conjunction with the aug-cc-pVTZ basis set. This leads to a standard heat of formation of AT//(21) = 724 6 kJmoH. ... [Pg.112]

Figure 12 shows the C CP/MAS spectra of PVA, sample I and sample II, where sample I and sample II are corresponding to PVA/PAA blends with PAA contents in monomer molar of 0.27 and 0.53, respectively. Three overlapped peaks ranged from 65 ppm to 77 ppm are attributed to methine carbon of PVA and are designated to peaks 1, 2 and 3, respectively (Fig. 13). The assignment of these three methine peaks, which had been an attractive...

WAXD scans from unhydrolysed polymer, -SO F, reveal that the polymer is semicrystalline. (Figure 2) This result is similar to the behavior observed in copolymers of tetrafluoroethylene, (TFE) with hexafluoropropylene or perfluoropropylvinyl ether. As the EW increases, the molar ratio of TFE to comonomer increases and the amount of crystallinity also increases. The amount of crystallinity, deduced from the relative intensity of the amorphous halo and crystalline peak, ranges between 0 and 40%, however, these values represent qualitative estimates rather than quantitative results. [Pg.196]

The semi-deterministic method already presented, based on the deconvolution of the UV spectrum, can be used as an alternative method for the rapid estimation of the phenol index . UV spectra are acquired from raw samples and, after a pH correction (pH = 12), in order to exploit both the bathochromic and hyperchromic effects, observed for the dissociated forms of phenolic compounds (phenates). This well-known procedure is particularly useful for nitrophenols, the spectra of which present a specific adsorption between 360 and 500 nm (Fig. 19). On the other hand, phenol and 2-chlorophenol have their adsorption peak range from 250 to 360 nm. It should be noticed that below 250 nm,... [Pg.105]

Mechanism of Action. The drug is a very rapid-acting insnlin which may be injected conveniently just prior to a meal. It exhibits an onset of action within a short span of 15 minutes besides having a relatively much shorter peak ranging between 0.5 to 1.5 hour, and having duration of action varying between 6 to 8 hours in comparison to the regular insulin injection . [Pg.671]
