| 摘 要： | 在785nm激发波长观测了乐果晶体及其熔体拉曼光谱,结果显示乐果晶体60℃熔化后在344,428和530cm-1处出现新峰,498cm-1处,(P-S)和648cm-1处,(P=S)峰强度发生反转,,(P=S)峰发生反常蓝移现象。这表明晶体结构长程有序性破坏对乐果拉曼光谱存在较强影响,在有关乐果溶液拉曼光谱实验和理论研究中应予以考虑。

| Abstract: | We detect Raman spectra of dimethoate crystal and melt at 785nm.The results show new Raman peaks appear at 344,428and 530cm-1 after dimethoate crystal melting at 60℃,the intensities of,(P-S)(～498cm-1)and,(P=S)(～648cm-1)are reversed,,(P=S)line takes abnormal blue shift.This indicates that the failure of crystal structure has large effect to Raman spectra of dimethoate,it should be taken into account in the experiment and theory research of dimethoate solution. |
