It was not until 1980 that the first spectrum of was discovered by Takeshi Oka, which was of the ? 2 fundamental band using a technique called frequency modulation detection.
2.
The lineshapes for overtone and combination bands tend to be much broader and more overlapped than for the fundamental bands seen in the MIR . Often, multivariate methods are used to separate spectral signatures of sample components.
