[求助] 拉曼光谱 具体的出峰位置 表征 急急急急急

想通过拉曼来表征Cd-S键的断裂以及O-Cd键的形成,不知道具体的出峰位置。。。以及Cd-Te键的峰的位置
想测原位的,本来是想测液体的。但是样品寄到别处去了,那人给我滴在硅片上然后测得,是不是最好要重新测得啊?
测液态样的话,要注意什么啊?参数什么的怎么测啊???
求各位大神们的指点!!!!
最好是能给我具体的文献,或者是告诉我怎么查的,在哪查到的^
因文章需要,急需这批数据。大神们帮帮忙啊!!!!!

the most prominent Cd-Te peak (LO peak) is about 165~170cm-1

Cd-O peaks: sharp peak at ~265cm-1(tentatively assigned to the second order transverse acoustic phonon mode, or 2TA mode), broad feature at ~390cm-1 (300~400cm-1 broad peak, two-PDOS)

the sharp peaks at about 500 and 1000 seem to be characteristic peaks of Si, and the one around 300 seems to be indicative of Cd-S. But in your case, in the second spectrum, peak at around 300 is still there. So it doesn't seem to be a process of breaking Cd-S bond and forming Cd-O bond. So I don't necessarily know what's going on there. the broad feature in your first spectrum could be resulted from some background (which can be baseline corrected I guess). The emerging of peaks at around 3000 I don't really know why.

那请问你知不知道O-Cd键以及Cd-Te键的峰大概会在什么的位置啊?
你有测过液态样的拉曼吗?要注意些什么啊?

The answer above is just a personal assessment based on published results. Whether they're right or wrong, you should make up the decision. Just a disclaimer.
I haven't done any Raman measurement on liquid sample. So not very sure what to be careful about.
