对非晶硒进行了Hartree-Fock从头算拉曼光谱计算和拉曼光谱测量，以确定由σ键引起的特征振动模式。作为带隙光照明的结果，观察到测量的峰强度的变化。基于我们以前的理论研究，我们起源于光诱导共价键断裂的强度变化。
Hartree–Fock ab initio Raman spectra calculations and Raman spectroscopic measurements were carried out on amorphous selenium in order to identify the characteristic vibrational mode due to sigma bonds. Variations in measured peak intensity were observed as a consequence of band gap light illumination. Based on our previous theoretical investigations we originate these intensity variations from photoinduced covalent bond breaking.
