Abstract
The vibrational relaxation time for pure SiH4 is 0.10, 0.083 and 0.072 μsec atm (±30%) at 295 K, 375 K and 462 K. For SiH4 diluted in He, D2 and H2 the corresponding numbers are 0.16, 0.081 and 0.031 μsec atm (± 30%) at 295 K. The binary two-level theory has been used to deter-mine the four V -R, T rates in the system SiH4 -CH4, and the rate for V-V exchange between SiH4 and CH4 from experimental data. From the Schwartz-Slawsky-Herzfeld-formula for V -T and V -V, T processes an equation is derived describing V -R and V -V, R energy exchange. The different models are compared with experimental data, especially with those found for the system SiH4 -CH4.Keywords
