  • 摘要

    由X射线之研究，知Ni(NO3)2•6NH3晶体中之NO3-有特殊之情形。本文由该晶体之拉曼光谱，研究在晶体中，晶体力场对NO3-之振动之影响•结果如在985cm-1处得一线。本文根据类似NH3之情形之“二最低能”问题，对Ni(NO3)2•6NH3,及Cu(NO3)2•3H20,Ce(NO3)3•6H20中NO3-之V1动振加以讨论。

     

    Abstract

    The Ramau spectrum ot Ni(NO8)3 6NH crystal is taken witln the view of studying thé effect of the erystal fiëld on the inner' vibrations of the NO3 group of-which a peculiar behavior is suggèstéd bý X-rey analysis. . Ono line is found at985 cm-1.This result and the spłitting of the V,~1050 cm-1 lino into a doublet in Gu(NO3)2 3H20 and Cu(NO;): 6H20 crystals.observed,by Ananthakri-' Rhnan aro discussed from the viewpoint of the §wo-minimum problem similar to the NHs molecule.
