Abstract
The hook method has been used to obtain oscillator strengths for twenty lines in three branches of the (0, 0) band of the 2∑+-2Π system of OH. It is found that vibration-rotation interaction decreases the effective f-value for this band by about 7% over the first ten lines of each branch. The absolute f-value obtained for the rotationless molecule is f00 = (14·8 ± 1·3) x 10-4. Although this falls within the range of previous measurements, it is nearly twice as large as the value hitherto considered most probable. For the (1, 0) band, in which vibration-rotation interaction could not be measured, the absolute oscillator strength is found to be (8·9 ± 1·7) x 10-4, giving for the relative oscillator strengths the ratio f10/f00 = 0·60 ± 0·10.Keywords
