The reagent is conveniently stored as a solution in isopropyl alcohol. The molten (or sobd) alkoxide is weighed out after distillation into a glass-stoppered bottle or flask and is dissolved in sufficient dry isopropyl alcohol to give a one molar solution. This solution may be kept without appreciable deterioration provided the glass stopper is sealed with paraffin wax or cellophane tape. Crystals of aluminium isopropoxide separate on standing, but these may be redissolved by warming the mixture to 65-70°.

Ammonium carbonate is obtained by passing carbon dioxide into aqueous ammonia solution in a column or tower. Ammonia, carbon dioxide and water vapor are distilled and the vapors condensed into a sobd crystaUine mass. It also may be prepared by subliming a mixture of ammonium sulfate and calcium carbonate. 

Elemental composition Ba 58.89%, Ti 20.53%, O 20.58%. The sobd is digested with a mixture of concentrated H2SO4 and HNO3, diluted and the aqueous solution is analyzed for the metals Ba and Ti by flame or furnace atomic absorption or ICP emission spectrophotometry. The compound in the crystalline powdered form may be identified by various x-ray techniques. 

Figure 15.8 Examples of spectral integration and normalization. Spectra shown were obtained with nitroxide label 14 (Fig. 15.3C). Acquisition parameters are listed in Table 15.1, except that number of scans = 4 and number of points = 1024. (A) Spectrum of an aqueous sample of a 23-nt RNA, together with its 1st and 2nd integrals. (B) Spectral comparison between a 23-nt RNA (40 gM, dotted line) and a 49-nt RNA (30 jiM, sobd Une). Comparison of the normalized spectra is not skewed by the different amount of labeled RNAs used in the measurement, and reports different nitroxide behavior due primarily to the difference in RNA size. (C) An example of spin counting. The calibration curve was generated by linear fitting (solid Une) of data points (sobd square) obtained using tempol solutions of various concentrations. Using this calibration curve, the sample measured in (A) was found to contain 37.5 gM of spins ( sample = 2.5). Based on an RNA concentration of 40 jiM, the nitroxide labeling efficiency was determined to be 93.6%.

As a result of having two chiial centers, four stereoisomers of ascorbic acid are possible (Table 1) (Fig. 2). Besides L-ascorbic acid (Activity = 1), only D-araboascorbic acid (erythorbic acid (9)) shows vitamin C activity (Activity = 0.025-0.05). The L-ascorbic acid stmcture (1) in solution and the sobd state are almost identical. Ascorbic acid crystallizes in the space group P2j with four molecules in the unit cell. The crystal data ate summarized in Table 2.

A number of points have to be considered. First of aU, the resolution in sohd-state NMR spectra is poorer than in solution, meaning that the isotope effects need to be larger in magnitude in order to be observed. Furthermore, residual dipolar couplings can give rise to splittings [56], which may be confused with isotope effects. Large equibbrium isotope effects are often observed for and F, so they seem to be excellent nuclei for the observation of isotope effect in the sobd state, but also can in certain cases be used. 

Boundary value problems (BVPs) involve the solution of ODEs or partial differential equations (PDEs) on a spatial domain, subject to boundary conditions that hold on the domain boundary. Many problems from sobd and fluid mechanics, electromagnetics, and heat and mass transfer are expressed naturally as BVPs. The forms of these differential equations often resemble each other because they arise from similar conservation principles. Here the emphasis is upon BVPs that arise from problems in transport phenomena.
