An investigation of the infrared spectrum of gaseous SiH2Cl2and the Raman spectrum of liquid SiH2Cl2results in the following fundamental assignment:ngr;1lpar;a1rpar;equals;2200thinsp;cmminus;1,ngr;2lpar;a1rpar;equals;953thinsp;cmminus;1,ngr;3lpar;a1rpar;equals;531thinsp;cmminus;1,ngr;4lpar;a1rpar;equals;188thinsp;cmminus;1,ngr;5lpar;a1rpar;equals;710thinsp;cmminus;1,ngr;6lpar;b1rpar;equals;2200thinsp;cmminus;1,ngr;7lpar;b1rpar;equals;810thinsp;cmminus;1,ngr;8lpar;b2rpar;equals;877thinsp;cmminus;1,ngr;9lpar;b2rpar;equals;592thinsp;cmminus;1.Thermodynamic functions for SiH2Cl2were calculated with the usual assumptions. The infrared spectrum of gaseous CH2Cl2and the infrared and Raman spectrum of liquid CH2Cl2were remeasured.
