Successive approximation for determining the hydroxyl rotational temperature.
A successive approximation is presented for determining the hydroxyl rotational temperature from a comparison of successively approximated intensities of the rotational lines, which are, in the state of raw data, resolved as the [P(1) (4) +P(2) (4)I, [P(1) (3) + P2 (3)1, and [P1 (2) + P(2) (2)l lines. It is found that the determination of rotational temperatures using this successive approximation is far less time-consuming and more convenient than the usual synthetic spectra method, especially in treating numerous spectra from OH bands. As an example, the nighttime variations of the rotational temperature obtained every 6 min with this successive approximation are presented.
