Figure 13.13 Summary of v(NC) peak assignments for CH3NC adsorbed on Pd/Al203. The peak at 2180cm is assigned to the on-top (T ) mode, the peak at 2050cm to the bridge linear mode, and the shoulder centered at 1850cm to the on-top bent (bentr ) mode [54].

A Finnigan MAT TSQ mass spectrometer was used to record the mass spectra of brinzolamide. The conditions were 0.3 mA current, 1100-volt acceleration voltage and 10 preamp sensitivity. The ionization voltage was 70 eV for El (electron impact) ionization mode. For Cl (chemical ionization) mode, a positive ionization voltage of 100 eV and a pressure of 0.3 torr of methane were used. The El and Cl spectra are shown in Figures 12 and 13, respectively. Peak assignments for the El and Cl spectra are listed in Table 6. Both the Cl and El spectra have an MH peak at m/z = 384. 

Typical HPLC chromatograms with peak assignments for several common fruits are illustrated in a book chapter by Wrolstad et al. (1994). While most of the chromatograms shown were generated using the Alternate Protocol, the pattern (elution order and relative peak areas) is essentially the same as for Basic... 

NMR and Raman peak assignments for natural gas and non-natural gas hydrates are listed in Tables 6.6 through 6.8, respectively. The NMR data presented are based on the works by Ripmeester and Ratcliffe (1998, 1999) and...

Oxidation of dialkenyl disulfides gave the stereoisomeric 2,3-dimethyl-5,6-dithiabicyclo[2.1.1]hexane 5-oxides 36 and 37, which are found in extracts of onion. Further conversion and oxidations afforded a series of various 2,3-dimethyl-5,6-dithiabicyclo[2.1.1]hexane derivatives, which were characterized on the basis of the comparative X-ray structural and NMR and IR spectroscopic data. The 111 NMR peak assignments for 36 and 37 were facilitated by LAOCOON III analyses of these 10 spin systems and by examination of the shifts induced by Eu(fod)3 and d6-benzene (fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octadione) <1996JA2790>.

The proton and 13C NMR spectra of a compound of formula C/tH N are shown here. Determine the structure of this amine, and give peak assignments for all of the protons in the structure. 

First, the cis-peak assignment for band III is primarily based on the theoretically estimated energy (54), which appears to be very sensitive to the choice of parameters in the calculation (48,93). In fact, recent theoretical considerations (93) show that changes in parametrization markedly affect the energy but not the relative intensity of the cis peak. The intensity criterion, which... 

Figures clearly distinguish the difference between these two TMS depositions on different substrate surface states. Table 33.1 lists the peak assignments for both (a) and (b). In Figure 33.1a, two distinct bands are observed near 3394 and 3190 cm These locations and peak shapes would be consistent with the presence of either isolated O-H bonds or N-H functionality. The strong, sharp peaks at...

High-resolution Si NMR spectroscopy was used to study the hydrolysis and condensation kinetics of monomeric and dimeric species in the silicate sol-gel system. Peak assignments for the kinetics experiments were determined by comparing add-catalyzed reaction solutions prepared with limited amounts of water with the synthetically prepared dimeric, trimeric, and tetrameric species. Si NMR peaks were assigned for 5 of the 10 possible dimeric species. The temporal evolution of hydrolysis and condensation products has been compared with a kinetic model developed in our laboratory, and rate constants have been determined. The results indicate that the water-producing condensation of dimeric species is approximately 5 times slower than the water-producing condensation of the monomeric species. The alcohol-producing condensation of dimeric species is comparable with that of monomeric species. 

NMR Assignments. Si NMR spectroscopy has been used extensively to probe silicate sol-gel reactions 8,10,12-23). Peak assignments for silicon nuclei depend on the next-to-nearest neighbor of the silicon atom being observed. With this approach, the degree of hydrolysis and condensation of a given silicon nucleus can be determined.

Fig. 6. One-dimensional water eliminated Fourier transform spectroscopy (WEFT) spectra of (A) wild-type amicyanin (B) the amicyanin mutant H96D (C) the amicyanin mutant H PFM H QGAGM (D) wild-type Pseudomonas aeruginosa azurin. The diamagnetic region from 9 to 1 ppm has been omitted from the centers of the spectra. The insets show the spectra in H2O, where an additional peak from an exchangeable proton appears. Peak assignments for wild-type amicyanin are given at the top of panel A. All spectra were collected at 32 C on samples containing 50 mAf phosphate, pH 7.0.
