Acoustical studies of rotational relaxation in gases.
It is shown that the use of ultrasonics for studying rotational relaxation involved two major unresolved problems. First, the data are not very precise, because rotational relaxation at room temperature occurs usually at frequencies above 300 MHz/atm, at which the absorption due to viscosity and thermal conductivity is much greater than that due to relaxation. The second problem is that simple relaxation theory is not applicable to the relaxation of systems whose rotational energy levels are not evenly spaced. The need for an improved theory is emphasized.
