Rate constants for reactions of SiFz radicals have been measured at 2 Torr in a high-temperature fast-flow system. The bimolecular reaction rate constant for SiF\*+F, over a temperature range of 282-617 K can be expressed as (1.0+0.25)X IO-"exp[ -(1850~2OO)lRT] cm3 molecule-' s-', where R is incal m

## Abstract The kinetics of iodine dioxide (OIO) reactions with nitric oxide (NO), nitrogen dioxide (NO~2~), and molecular chlorine (Cl~2~) are studied in the gasβphase by cavity ringβdown spectroscopy. The absorption spectrum of OIO is monitored after the laser photodissociation, 266 or 355 nm, of
The reaction of chlorine atoms with iodomethyl-methyl ether ICH2OCH 3 was studied over the temperature range 273-363 K using the very low pressure reactor technique. The absolute rate constant was measured at various temperatures, and was given by the expression k = (1.53 \_+ 0.82) x 10-i i exp[(1.4
The infrared multiphoton decomposition of Si2F 6 has been investigated by time-resolved infrared diode laser spectroscopy. Direct formation of SiF2 ()(IA~) in the ground vibrational state and indirect formation via vibrational relaxation were found. Simultaneous formation of SiF4 with SiF2 was also
SiF and SiF2 radicals, produced in the thermal reaction of Fz and NF:, with solid silicon, have been detected by multiphoton ionization mass spectrometry in the 438 and 321 nm wavelength regions, respectively. The reaction pathway to the production of SiF radicals is of minor significance compared w
