Abstract

The complete labeling pattern of ergosterol isolated from Saccharomyces cerevisiae grown with [1‐^13^C] acetate is detailed and the results of this study have led to a reassignment of carbons 5, 8, 12, 16, 22 and 23 in the ^13^C n.m.r. spectrum of ergosterol.

The Raman spectrum of cyanogen 13C214N2 has been investigated at nearly Doppler resolution by means of a stimulated Raman technique. The regions around the bandheads of the nu1 (2260 cm-1) and nu2 (835 cm-1) vibrations have been recorded. Besides the fundamentals, hot bands arising from v5 = 1-3 and
