Spectrophotometry uses what to identify drugs?

Spectrophotometry uses light to help identify drugs.

Explanation:

Spectrophotometry is a physicochemical method for studying solutions and solids based on the study of absorption spectra in the ultraviolet (200-400 nm), visible (400-760 nm) and infrared (> 760 nm) spectral regions. The main dependence studied in spectrophotometry is the dependence of the absorption intensity of the incident light on the wavelength. Spectrophotometry is widely used in the study of the structure and composition of various compounds (complexes, dyes, analytical reagents, etc.), for the qualitative and quantitative determination of substances (determination of trace elements in metals, alloys, technical objects).
