以高分辨率记录了sih4、Si(ch3) 4、c2h5 sih3、(ch3) 2sih2、(ch3) 3sih、sif4、sicl4、(ch3) 3sicl、(ch3) 3sii、cl2sih2、ch3 sif3等11种分子的硅2p光电子能谱。光谱都表现出变宽,在某些情况下,由于核电离分子的振动激发而分解出精细结构。广泛使用等效核近似来帮助解释观测到的振动结构
The silicon 2p photoelectron spectra of eleven molecules: SiH 4 , Si(CH 3 ) 4 , C 2 H 5 SiH 3 , (CH 3 ) 2 SiH 2 , (CH 3 ) 3 SiH, SiF 4 , SiCl 4 , (CH 3 ) 3 SiCl, (CH 3 ) 3 SiI, Cl 2 SiH 2 , and CH 3 SiF 3 , have been recorded at high experimental resolution. The spectra all exhibit broadening, and in some cases resolved fine structure resulting from the excitation of vibrations in the core-ionized molecules. Extensive use is made of the equivalent-cores approximation to aid in the interpretation of the observed vibrational structure
