“…After irradiation of the sample, absorption in the region from 386 to 486 nm with the maximum at 430 nm was detected. This absorption corresponds to the absorption of dimethylgermylene described in previous studies [7,9,[11][12][13][14][15]17]. The absorption in the region from 200 to 350 nm observed after photolysis was similar to the TPN spectrum in liquid solution and did not precisely agree with the low-temperature spectrum of TPN.…”

“…An attempt at RRKM modeling of the observed pres sure dependence based on the following reaction scheme (which actually is analogous to the scheme used in the RRKM modeling of the GeH 2 + C 2 H 4 system, see above), failed: (17) An unreasonably high value of the critical energy (305 kJ mol -1 ) was found to be necessary to reproduce the experimental pressure dependence. 75 This implied the existence of an additional, irreversible, reaction channel, efficiently removing the vibrationally excited intermedi ate prior to stabilization.…”

“…As mentioned previously, the peak at 540-560 nm has been tentatively assigned to diisopropylgermylene 2 [8], in spite of the fact that dialkylgermylenes are reported to absorb in the 420-490 nm range [9][10][11][12][13][14][15][16]. In addition, the lifetimes of dialkylgermylenes in inert solvents such as cyclohexane are usually as long as several microseconds, and the decay of dialkylgermylenes show second-order kinetics because dialkylgermylenes dimerize to form tetraalkyldigermenes [11][12][13][14][15].…”
