It provides critical insights into the molecular structure and composition of materials by measuring their infrared absorption spectra. This article delves into the definition, principle of operation, ...

115, No. 805 (March 2003), pp. 389-409 (21 pages) ABSTRACT We present a method for correcting near‐infrared medium‐resolution spectra for telluric absorption. The method makes use of a spectrum of an ...

QCL-IR spectroscopy is based on the well-acknowledged Beer-Lambert absorption concept. It is, therefore, a technique for not just spectrally fingerprinting unknown chemicals but also directly ...
