用微波波谱法在17-39 GHz范围内测量了HC_4OH及其氘代物种的转动光谱。该光谱是在830°C下热解2-丁炔醇之后产生的;通过将2-丁炔醇与氘代水蒸气混合引起产生DC 4 OH和HC 4 OD的氘代反应。精确测定了HC 4 OH的转动常数B和C，测定了DC 4 OH和HC 4 OD的转动常数（B + C）/2。有了这些旋转常数，HC 4 OH的整个无线电频谱可以准确地估计，在高达51.1 GHz的频率下，精度优于0.42 MHz。这些跃迁频率对于天文学上识别这种分子应该有很大的用处。
The rotational spectra of HC4OH and its deuterated species have been detected in the 17-39 GHz region by microwave spectroscopy. The spectra were generated after pyrolysis of 2-butynol at 830°C; a deuteration reaction to produce DC4OH and HC4OD was caused by mixing the 2-butynol with deuterated water vapor. The rotational constants B and C were precisely determined for HC4OH and the rotational constant (B + C)/2 was determined for DC4OH and for HC4OD. With these rotational constants, the entire radio spectrum of HC4OH can be accurately estimated to better than 0.42 MHz accuracy at frequencies up to 51.1 GHz. These transition frequencies should be of great use for astronomical identification of this molecule.
