(under subclass 300) Subject matter which includes a directed beam of light, means to support transparent gaseous, liquid, or solid substances for transmission of the beam through the substance, and means transverse to the direction of the beam for detecting the light reflected or scattered by the molecules of the substance, and including the detection of the light caused by change of the rotational and vibrational energy of the molecules due to the light energy directed through the substance.
