## Abstract The preferred conformations of the four isomers of 1,2,3,4,4a,6,7,8,9,13b‐decahydro‐9a__H__‐pyrido[1,2‐__f__] phenanthridine have been determined by 270 MHz ^1^H n.m.r. and i.r. spectroscopy. N.m.r. assignments are based on the specific chemical shifts of the protons adjacent to the nit
