The CO2 cw laser induced interaction of sulfur hexafluoride with chlorine, silicon tetrachloride, trichlorosilane, and methyltrichlorosilane in a glass reaction vessel has been investigated. The reaction of SF6 with glass surface yielding silicon tetrafluoride and thionyl fluoride was observed. It is inhibited by the products and its rate increases with growing initial pressure (0.6-5.3 kPa) of SF6. Presumed vibrationally excited or dissociated SF6 undergoes the same reaction in the presence of chlorine and silicon tetrachloride, too. The reaction is suppressed by the addition of trichlorosilane and methyltrichlorosilane; in these cases SiF4, SiCl4 and HCl, or SiF4, SiCl4, HCl, acetylene and carbon disulfide are formed. The products indicate a non-sensitizing action of SF6 and a specific reaction channel for the formation of CS2 not attainable by pyrolysis.

The imidovanadium(III) complexes [tBuN=VCp(PR3)2], [tBuN=VCp{P(OR)3}2] and [tBuN= VCp(CO)2] have been prepared starting from tBuN=VCpCl2 by reductive dehalogenation with magnesium. The reaction of [tBuN=VCp(PMe3)2] (2a) with carbon monoxide, alkynes, alkenes, tert-butylphosphaalkyne, nitriles, ketones and carbon disulfide furnished the complexes [tBuN=VCp(PMe3) (L)], while the vanadium(V) compound tBuN=VCp(O2C2Ph2) is formed with benzil. All vanadium(III) complexes obtained are diamagnetic (d2, low-spin configuration) and have been characterized by spectroscopic methods (MS; 1H, 13C, 31P, 51V NMR).

Infrared chemiluminescence attributed to the first overtone of CO was observed when either C2H2 or was introduced into a stream of oxygen which had been passed through a microwave discharge. The addition of vibrationally cold CO to these systems was found to produce a vibrational population inversion in the chemically formed CO. CO first overtone emission was not observed when CH4 was introduced into a similar stream of oxygen unless the CH4 had been subjected to a microwave discharge. These observations are used to clarify the mechanisms governing the formation of CO in continuous wave air–helium–hydrocarbon electrical discharge lasers.
