Title: Measurement of the absorption cross sections of SiCl4, SiCl3, SiCl2 and Cl at H Lyman-alpha wavelength

Journal/Source: Chem. Phys. Lett., 561-562, 31-35, (2013); http://dx.doi.org/10.1016/j.cplett.2013.01.035


Data: table

Energy/Wavelength range: 121.6 nm

Resolution: 

Temperature: 300 - 2100 K

Temperature dependence: yes

Pressure/Concentration: ~ 150 kPa

Comments: Using time-resolved absorption profiles at 121.6 nm and a detailed reaction model, the absorption cross sections 
of SiCl4, SiCl3, SiCl2 and Cl have been measured. For silicon tetrachloride, the cross section is temperature independent in the 
300-2100 K temperature range whereas the cross sections for SiCl3 and SiCl2 decrease exponentially and increase exponentially 
for chlorine atoms.
