[求助] 红外光谱求教

近日做了氧化钛和碳掺杂的氧化钛,得到一组红外光谱。文献显示500多的峰可以归属于Ti-O键的面内弯曲振动。纯的氧化钛在521cm-1处,掺杂后在531cm-1处,根据文献可归属于C-O-Ti的形成。导师说可以根据这个波数计算出Ti-O键键长,请教各位高手,我应该怎么做呢?

Ask your teacher to calculate the bond length.

Usually, IR bands can explain the interactions and prove the components.  It is quite difficult to calculate the bond length, because the peak position is largely effected by the state of your sample and interaction of near molecules.  Of course, different resolutions of IR spectrum will show different location of the same peak.
