李时珍石的红外与拉曼光谱

Infra-red and Raman spectra of the Lishzhenite

李时珍石是一种硫酸盐新矿物，理想分子式为：ＺｎＦｅ＿２（ＳＯ＿４）＿４·１４Ｈ＿（２）Ｏ。属三斜晶系。空间群Ｐ，Ｚ＝１。本文首次报导它的拉曼光谱，并结合红外光谱，以及与它的类质同象物─—粒铁矾的振动光谱对照，对李时珍石的振动光谱的主要谱带的归属作了探讨。

Lishizhenite is a new deposit of sulphate，the ideal chemical formula is ZnFe_2（SO_4）_4· 14H_(2)O. Lishizhenite belongs to triclinic system，space group P，Z＝1. In this paper， the Raman spectra was first reported．Comparing with the vibrational spectra of its isomorphic，roemerite，and combining with the IR spectra，we discussed the assignments of main bands of Lishizhenite＇s vibrational spectra.
