Infrared spectroscopy also termed as vibrational spectroscopy is used for analysis and determination of different functional groups and compounds in different areas and mainly in pharmaceutical field. It is an easy and accurate method for functional group determination. Principle behind this is the measurement of the molecular bond vibrations of compounds, excited by radiation of a suitable frequency, when given the conditions for energy absorption by the molecules. Fourier transform infrared spectroscopy (FTIR) and Attenuated transmission reflectance (ATR) Spectroscopy are the new advancement in measurements of IR. Both can be used for qualitative and quantitative analysis of different substances. Here, we review the potential applications of FTIR and ATR for use in analysis of drugs. Vibrational spectroscopy has shown high potential as a novel method of analysis.
