RECENTLY one of PO (G.L.) de8oribed the preparation of azothio-bensene8, the aulphur-analogue8 of azoqbenaene8, by the action of 8odium metal in boiling toluene 8olution on the oorrr8ponding thi+l8niliner; la good evidenoe wa8 obtained a8 to the propo8ed 8truoture of the reaction product8 from their chemical reaotivity la end ultra-violet 8peotra.lb From Our knowledge,2 there doe8 not appear to be any 8peoifio infra-red study on organio moleoale8 containing NS bonds, owing perhap al8o t0 the 8omewhat unoolllllon ooourrence of muoh bonds, We give here briefly 8om8 rehvant infra-rod data pertaining mainly to the -NHs-part of our molaoule8, while a 31lore detailed report on the infra-red work i8 being prepared for Leendri aud P Reborr Exwrientia 1 , 503 (1457); b h.

An investigation of the influence of angular strain on the stretching vibration of carbonyl groups fa cyclic ketones is made. The results obtsined by a normal coordinate treatment show that frequency variation is due both to kinetic energy and potential energy effects.
