Crystal can be crystallographically oriented by molecularspectrum 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。

One way to find out would be to measure the planet's light spectrum, which could reveal molecular oxygen or other possible signs of life in its atmosphere.
一种测量方法是测量这颗行星的光谱，这样可以探测到其大气中是否有氧气或其他生命迹象。

The hydrophobic monomer and polymer were characterized by the infrared absorption spectrum, and then the molecular structure was confirmed.
