Several phenyl alkyl ketones display two overlapping short-lived pilosphorescenccs at 77"K, with O-O bands at 384 nm (74.5 kcal) and 397 nm (72.0 kcal). The hgher energy emission (T = S-10 msec) is favored in rigid methylcyclohesane glasses, while the proportion of lowcr-encrgy emission (T = 4-5 mse

Dielectric absorption studies have been made (with one exception) in the ranges ED-280K and IO\*-IO5 Hz of eight ketones of the type C6H5COR where R is varied from CH3 to C10H2, in a polystyrene matrix. An intramolecular relaxation process has been found in each case with an enthalpy of activation o
