| Abstract: | V ? R,T deactivation of the ν4 (243 cm?1) level in BCl3 by HCl has been measured over the range 220–340 K, with an infrared double resonance technique. The deactivation probabilities show an inverse temperature dependence below room temperature, indicating that long-range attractive forces are important in the resonant transfer process. The results are compared with the theory of Sharma and Brau. |
