Abstract

Optical absorption measurements between 300 and 50000 cm-1 in the 12 to 300 K temperature range, on thin films of (SN)on radicals deposited from (SN)x vapors, are presented. The spectrum of a thin film deposited at 12 K is interpreted as arising from the SN vibrational modes and electronic transitions of the ring S4N4 molecule, the linear (SN)ox radical and an (SN)on radical longer chain length. The temperature induced evolution of the optical spectrum and the probable nature of the polymerized blue-black films, shown by preliminary X-ray data to be non-crystalline, are discussed.
