斜方晶系和单斜正构烷烃的红外活性亚甲基摇摆-扭曲基本原理的振动相关分裂模式已被确定和分析。偏振测量表明两种结构的分裂模式不同。简单的二参数耦合振荡器模型解释了观察到的 c 轴色散曲线的形状。建议该分析的结果可能有助于确定包含长链烃分子的晶体中涉及的堆积类型。
Vibrational correlation‐splitting patterns for the infrared active methylene rocking–twisting fundamentals of the orthorhombic and monoclinic n‐alkanes have been determined and analyzed. Polarization measurements show that the splitting patterns are different for the two structures. A simple two parameter coupled oscillator model accounts for the observed shapes of the c axis dispersion curves. It is suggested that the results of this analysis may be useful in establishing the type of packing involved in crystals containing long‐chain hydrocarbon molecules.
