Nuclear magnetic resonance spectroscopy (NMR) was first developed in 1946 by.UV-visible spectroscopy This chapter outlines the basic theories and principles of UV.

The high pressure in the hydrogen lamps causes the hydrogen to emit a continuum rather than a simple hydrogen spectrum.

Theory of Ultraviolet-Visible (UV-Vis) Spectroscopy

This course describes the basic theory of UV-visible spectroscopy,.

Convex lens: Gathers the beam of radiation and focuses it on the inlet slit.It provides a supply of radiation in the wavelength range varying between 320- 2500nm.The foresaid phenomenon continues until the entire cascade of electrons is collected ultimately at the so called collecting electrodes. 28 RECORDING DEVICE: RECORDING DEVICE The signal from the detector is finally received by the recording device.This article provides an overview of the basic principles of spectroscopy as applied. instrumentation,. absorbance spectroscopy.
