## Abstract Carbonβ13 NMR study of 4(5)βvinylβ1,2,3βtriazole in dimethylformamide at β55Β°C allows direct observation of the three separate tautomers. The ^13^C chemical shift values of the three forms, as well as their percentages in the tautomeric mixture, are given.
The "C NMR chemical shifts for a series of substituted tricycle[ 5.3.0.02.6] decan-3-ones and tricycle[ 5.4.0.02~6]undecan-8-ones derived from [ 2 + 21 photoaddition reactions are assigned and the influence of various substituents is discussed. In general, it was found that substituent shifts are le
