High Resolution Studies of Atoms and Molecules

Abstract

During the project period of two years, the following steps were taken to ‎accomplish the research project: ‎1-‎ The relevant data for molecules were collected and the experimental ‎work was initiated.‎ ‎2-‎ Under the permanent equipment head, a dual pen chart recorder from ‎Cole Parmer (USA) was imported and installed to record ‎simultaneously the reference standard and the absorption spectrum. ‎Two vacuum gauge systems were also acquired.‎ ‎3-‎ The absorption spectra of lithium, potassium and sodium were ‎photographed using the locally fabricated 3 meter spectrograph for ‎which the financial support was provided by the Pakistan science ‎Foundation under project no: PSF(54).‎ ‎4-‎ The spectrum of lithium dimer, potassium dimer and sodium dimer ‎were also recorded using the Nd:YAG and the dye lasers in ‎conjunction with the thermionic diode.‎ ‎5-‎ The experimental results have been published
