Recording (black trace) of the imidazole rotational spectrum in the 3 mm region taken with the W-band segmented chirped-pulse spectrometer at DESY. The red histogram (inverted) indicates the predicted positions of the a-type lines computed using the spectroscopic parameters of Table 2. The b-type transitions (blue trace) are very weak and barely visible in the used y-axis scale.
