Observation of Resonance Raman Scattering below the Dissociation Limit in I 2 Vapor

摘要: Inelastic photon scattering from ${\mathrm{I}}_{2}$ vapor was observed to change resonance Raman fluorescence as a single-mode argon laser tuned through the 5145-\AA{} gain profile. 3 orders of magnitude enhancement in Stokes and first-overtone intensities were measured going fluorescence. The intensity distribution first 47 overtones is shown for frequency coincident with $43\ensuremath{\rightarrow}0 P(12)$ R(14)$ transitions ${B}^{3}\ensuremath{\Pi}_{0\mathrm{u}}^{+}\ensuremath{\rightarrow}{X}^{1}\ensuremath{\Sigma}_{0\mathrm{g}}^{+}$. cross section compared ${\mathrm{N}}_{2}$ found be 2.6 \ifmmode\times\else\texttimes\fi{} ${10}^{6}$.
