This video is about difference between UV, Visible, and IR Spectrophotometers. Apart from that, some miscellaneous components such as beam splitter, optical chopper, servo meter, and optical wedge were discussed. Additionally, mechanism of null detector and ratio recording method was explained. The reference material has been taken from the book "Organic Spectroscopy and Chromatography" by Dr. M. Younas.
