Abstract
The rate constants for the reactions of the DS radical with NO~2~ (reaction 1) and ClNO (reaction 2) have been measured using the dischargeβflow technique at 2 torr total pressure of helium. The DS radical was monitored by laserβinduced fluorescence. The reactions were found to have the following bimolecular rate constants (95% confidence level, in units of cm^3^ molecule^β1^ s^β1^):
This expression for k~1~ is found to be in excellent agreement with one of several previous studies. The magnitude of k~2~ is examined within the framework of a wellβestablished reactivity trend. Β© 1994 John Wiley & Sons, Inc.
