Observation of the infrared spectrum of the hydrogen molecular ion HD/sup +/. [6 and 7 GeV/c]

Journal Article · · Phys. Rev. Lett.; (United States)
The vibration--rotational spectrum of the hydrogen molecular ion HD/sup +/ has been observed by means of a new ion-beam laser-resonance method employing Doppler-effect tuning and collisional detection. Six transition-frequency groups between 1642 and 1869 cm/sup -1/, exhibiting partially resolved hyperfine structure, have been measured to +- 1 ppm. The accuracy exceeds that of present theoretical calculations of HD/sup +/ energy levels. (AIP)
