测量了（H_2O）_2的（Ka= 0，lower）→（Ka= 1，upper）和（Ka= 1，lower）→（Ka= 2，upper）带的转动隧穿跃迁。虽然这些转变中的一些已经在早期的出版物中报道，更详细的讨论的实验和结果在这里。使用速调管或边带的谐波，在连续缝隙喷嘴膨胀中通过直接吸收光谱测量了跃迁。这些数据沿着与以前的测量已经使用IAM样处理进行了分析。更好地确定了转动常数和最大隧穿分裂的值。
Rotational tunneling transitions have been measured for the (Ka= 0, lower) → (Ka= 1, upper) and the (Ka= 1, lower) → (Ka= 2, upper) bands of (H2O)2. Although some of these transitions have been reported in an earlier publication, a more detailed discussion of the experiment and of the results is presented here. Transitions have been measured by direct absorption spectroscopy in a continuous slit nozzle expansion using either harmonics from klystrons or sidebands. These data along with previous measurements have been analyzed using an IAM-like treatment. A better determination of theArotational constant and of the value of the largest tunneling splitting has been achieved.
