Conformations and configurations were assigned to several N-Me imines and N-alkyl acetaldimines from analyses of their 60-Mc NMR spectra. All aldimines exist exclusively in the syn configuration. Interpretation of the vicinal and long-range (across 4 and 5 and bonds) spin-spin coupling constants of N-Me aldimines led to the conclusion that I and II are the minimum energy conformations of these compounds

N.m.r. and i.r. spectra are reported for 19 imines of the type PC[graphic omitted]N–C[graphic omitted]QR (P = alkyl or aryl and Q, R =(H,alk), (alk,alk), or –[CH2]n–). The variation in |Jab| with structure is examined, and evidence is found for conformational effects similar to those for allylic coupling. The CN stretching frequencies fall into characteristic and separate ranges for P = alkyl and P
