Crystal can be crystallographically oriented by molecular spectrum with the change in band shift, band intensity, and band shape.
利用分子光谱谱带位移、谱带强度、谱带形态等的变化,可以初步对晶体作结晶学定向。
With wear, the band stretches and then you'll want to shift to the tightest closure.
和其他衣服一起穿时,背带伸直,你会想把它提至最高位置。
The spectra have been assigned theoretically and the red shift of spectral band from molecule to cation has been discussed.
对光谱进行理论指认并讨论了从中性分子到离子谱带红移的原因。
