Nuclear magnetic resonance spectroscopy

“…COMPUTER APPLICATIONS Structural interpretation of first-order NMR spectra by computer (390), a new algorithm for calculation of NMR spectra (391), a program for retrieval and assignment of chemical environments and shifts to facilitate interpretation of 13C NMR spectra (392), a program for analyzing NMR of polycrystals (393), a computer system for data acquisition and evaluation (394), computation of NMR powder line shapes for quadrupolar nuclei (395), FOCAL computer programs for NMR (396), a lineshape function for absorption mode double NMR spectra (397), a computer program for simulating many-spin NMR spectra (398), deconvolution of broad-line NMR spectra (399), electronic data processing of the parameters of impulse Fourier transform 13C NMR spectra (400), computer simulation of multipulse and Fourier transform NMR experiments (401), precision in measuring NMR spectra (402), determination of fluoroolefins from measurement of area intensity of sharp 19F NMR signals by use of a minicomputer coupled with the sawtooth sweep (403), and an automated data collection system for T\ and T2 determinations (404) have been described. Computer simulation of time-dependent processes and saturation phenomena in an AB spectrum for intramolecular chemical exchange (405) has been reported as has the use of computer line narrowing in the UB Fourier transform NMR spectra of nido-carboranes (406). Computer analysis of the temperature dependence of NMR spectra during intramolecular exchange ( 407) and the interand intra-molecular exchanges in 1,4-dimethylhexahydro-l,2,4,5-tetrazine (408) has been presented.…”
