Question

Factors that affect the width of spectra in spectroscopy?

Answer 1

Answer:

Determines the natural width of a line (generally very small). reduce the effective lifetime of a state, leading to broader lines. High pressure gives more collisions (eg stars). the thermal (or large-scale turbulent) motion of individual atoms in the gas relative to the observer.

Answer 2

Answer:

It determines the natural width of a line. Reduce the effective life time of a state, leading to broader lines. High pressure gives more collisions(e.g. stars). The thermal motion of individual atoms in the gas relative to the observer.
