The Ramanspectrum of liquid N-(fluorosulfonyl)imidosulfurous difluoride FSO2N = SF2 and the IR spectrum of its vapour phase were recorded. The observed features in combination with the theoretical studies indicate the existence at room temperature of only one conformer. In accord with previous results obtained by electron-diffraction analysis, this single conformer possesses C1 symmetry in which the
记录液态N-(氟磺酰基)亚氨基二氟化硫FSO 2 N = SF 2的拉曼光谱和其气相的IR光谱。观察到的特征与理论研究相结合,表明在室温下仅存在一个构象异构体。与通过电子衍射分析获得的先前结果一致,该单一构象异构体具有C1对称性,其中SF2基团相对于NS单键同向取向。还使用从头算和密度泛函理论(DFT)计算在不同的近似水平下确定了理论振动光谱。对于除扭转模式之一以外的所有形式,获得了实验波数。随后使用通过理论方法计算出的扭转波数进行法线坐标分析。
