The Raman spectrum of N2 isolated in an argon matrix at 4.2[...]K was obtained using single photon counting techniques and a CW argon ion laser. Attempts at measuring the vibrational relaxation (VR) time for N2 were made by monitoring the Raman intensity from upper vibrational levels as a function of time. Stimulating the Raman process using a rhodamine 6G jet stream dye laser tuned to the Stoke's frequency while simultaneously irradiating with the argon ion laser, was also attempted in an effort to improve Raman intensity. Although an accurate measurement of the VR time awaits a more efficient excitation process (or a more powerful laser), our results indicate a VR time as long as a few minutes is possible for N2 in this environment.
