one obtains the electronegativity XNSF, = 3.3. If one plots the mean P F frequency of the phosphoryl halides against the sum of the electronegativities, one obtains a linear dependence, whence the electronegativity of the NSF2 group again appears as 3.3. Compound (4) IS a clear liquid of b.p. 7 2 Β°C
Formaldehyde/oxygen/nitrogen mixtures were photolyzed with UV light in a gas flow system. The reaction mixtures were analyzed by pumping a small fraction of the flowing gas through a microprobe, trapping the condensable compounds on a cold finger (T=96 K), and measuring the ESR spectrum of the solid
