✦ Synopsis

When gaseous SO2 was exiled to the vibronic levels of thee 'BI state just below the predissociation threshold, its fluorescence was found to be quenched remarkably by external magnetic fields below I2 kG in a collision free condition. From the vibrational energy dependence and the field strength dependence, the magnetic quenching could be interpreted in terms of the radiationless transition in a magnetic field. The relation between the quenching and the predissociation of SO* was also discussed.

Magnetic field effects on the banded emission from the V 'Bt state of CS2 have been studied. A magnetic field was found to decrease the integrated intensity of the fluorescence excitation spectrum and to shorten the lifetime of a picosecond component. These results indicate that a magnetic field enh
