Rk. Vatsa et al., UV SPECTRUM AND DECAY KINETICS OF TRANSIENT METHYLSILENE PRODUCED IN THE 193-NM PHOTOLYSIS OF GASEOUS 1-METHYL-1-SILACYCLOBUTANE, Chemical physics letters, 255(1-3), 1996, pp. 129-133
193 nm photolysis of gaseous 1-methyl-1-silacyclobutane with a laser f
luence of 50 mJ cm(-2) yields a H2C=Si(H)CH3 transient, which decays e
xclusively by dimerisation to form 1,3-dimethyl-1,3-disilacyclobutane
as the stable product with an estimated rate constant of (2.4 +/- 0.5)
x 10(-11) cm(3) molecule(-1) s(-1).
