β¦ Synopsis
Using a state-selective optical technique, we have measured the non-equilibrium distribution function f in heat-conducting iodine gas as a function of the rotational and vibrational energy. This is the first experimental proof that in the expansion off; the contribution of polynomials quadratic in the rotational or vibrational energy is substantial.
