## Abstract A ^13^C NMR study of a number of substituted 1,5‐benzodiazepin‐2‐ones has been carried out, and shows that this technique is one of the rare spectroscopic methods which allows an unambiguous identification of the number and nature of the isomers formed in the condensation of a β‐ketoest

✦ Synopsis
Abstract
^13^C NMR spectroscopic data are reported for the s‐triazolo‐as‐triazinones of five isomeric series. Comparison of their ^13^C chemical shifts and CH coupling constants allows the determination of the type of ring junction of the two heterocycles, as well as the predominant tautomeric form in each system.

## Abstract It is demonstrated that in a case where neither the proton nor the natural‐abundance ^13^C‐satellite spectra of a partially oriented molecule carry enough structural information, one can determine the entire molecular geometry by the combined use of several liquid crystals as solvents.
