摘要:

Laser spectroscopy of the cesium dimer is presented for use in an undergraduate laboratory. The experimental apparatus consists of near 780‐nm diode lasers, a glass cesium cell, a simple oven, and a monochromator. The experiment can be assembled quickly and at low cost. In the course of this experiment students can observe vibrational structure in molecular emission and learn about potential energy curves and Franck–Condon factors. The first vibrational constant of theX1Σg+ground state is measured to be 42.7±1.6 cm−1.
