摘　　要：Infrared absorption spectroscopy offers fingerprint identification of molecular analytes through their vibrational or rotational degrees of freedom.However,the absorption cross-section of a single molecule is very small because the size of the molecule is far smaller than the wavelength of light,typically ranging from 2.5 to 25μm.Therefore.

关 键 词：ABSORPTION VIBRATIONAL typically
