Labeled derivatives of N-methylolacrylamide (NMA) including 15 N-NMA, 13 C-NMA, and 13 C, 15 N-NMA were synthesized and purified. A required chemical precursor, 15 N-acrylamide, was also prepared. Reported methods for synthesizing unlabeled analogs are noted, and modifications to these methods for a

✦ Synopsis
The high resolution infrared spectrum of the linear centro-symmetric molecule 13 C 2 15 N 2 (cyanogen) has been measured in the region from 1950 to 2150 cm 01 . The n 3 fundamental band and the difference band n 1 -n 5 were observed in that region. Hot-band transitions arising from the n 5 , 2n 5 , 3n 5 , and n 4 levels were also measured with the n 3 band. The n 3 fundamental band and first hot band for 15 N 12 C 13 C 15 N were also measured.
