Magnetic field effects on the photoionization yield of N.N,N',N'-tetramethyl-p-phenylenediamine in deaerated 2-propanol have been studied by transient photoconductivity measurements. The photocurrent increases by about 15% in the presence of a magnetic field (720 mT). The results are interpreted in

## Abstract A vibrational study of two crystalline forms of the __N__,__N__′‐diphenyl‐1,4‐phenylenediamine molecule is reported. This compound shows polymorphism in its solid state, i.e. either an orthorhombic or a triclinic structure is obtained depending on the conditions of crystallization. Thre
