✦ Synopsis

The optical band shape for the At? -Eu transitian in D4h symmetry has been caIcuIated quantum mechanicaily. it is shown that the band shape for modcrateiy strong coupling with two vibrational modes has a doubly peaked structure even if the two coupling constants are different and the two vibrations have difikent frequencies. The caiculation is compared with experiment and qualitative agreement is found.

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 a
