Some new 10-N-acylamino phenothiazine& have been prepared and their ultraviolet and infrared spectra have been discussed. An attempt has been made to show the N-acyl substitution effects on the course of absorption pattern of phenothiazines, It was interesting to find that N-acyl substitution showed bathochromic shift in the U.V. spectra of these compounds and carbonyl peaks in the I.R. spectra have been shifted to higher region by 20-35 cm^-1.
