✦ Synopsis
We report absorption spectra from the ground state to the photoexcited triplet state of platinum porphin (PtP) in single crystals of n-octane (ca) and n-decane (Clo) at 4.2 K, with and anthout a magnetic field. For PtP in C1o the same transition was studied m emission. From the euperunents, values are derived of the spin-orbit coupting parameter 2, tke crystal field sptittmg 6 and the orbrtat angular momentum A for PtP m the two hosts: 2 = 76 k 2 cm-' (Ca. Cro), 6 = 71 f 1 cm-' (Ca), 55 * 1 cm-' (Clo) and A = 1.6 5 0.1 (Cal C&O). For the ratio of the in-plane and the z-polarized electnc dipole transition moments we obtam IfifX,yl/iM.i = 7 6 z 0.3 (Ca).
