## Abstract The ^13^C,^15^N coupling constants in three 1,2,4‐triazine‐4‐^15^N derivatives and in a substituted pyrimidine‐1‐^15^N have been determined and are compared with those in pyridine and quinoline. Of special interest are the data of the 5‐(2‐dimethylamino‐1‐propenyl)‐3,6‐dimethyl‐1,2,4‐tr

## Abstract ^15^N labeled tetranitromethane, C(^15^NO~2~)~4~, was prepared from anhydrous nitric acid and acetic anhydride. A procedure for the preparation of the nitric acid from Na^15^NO~3~ is described. Tyrosine was nitrated with H^15^NO~3~ and its ^15^N NMR spectrum compared well with that of t
