Formyl (HCO) molecules have been found in the interstellar medium (ISM) at least a dozen times so far, suggesting that there are more to be found. However, high-resolution spectroscopic data for these kinds of small molecular species are still lacking, making it difficult to detect them. Experiments were conducted to determine the rotational spectrum of glutaronitrile. An FTM spectrometer was used to study the rotational spectra of glutaronitrile's supersonic jet between 6 and 20 GHz. In addition, the mmW spectrum was detected in the frequency range 72−116.5 GHz using a broadband millimetre-wave spectrometer based on radio astronomy receivers with rapid Fourier transform backends. Calculations at the highest degree of ab initio were used to support the spectroscopic searches. The gg conformer of glutaronitrile was found to have 111 rotational transitions with maximal J and Ka quantum numbers of 54 and 18, respectively. We were able to precisely calculate the rotational, nuclear quadrupole coupling, quartic, and sextic centrifugal distortion constants thanks to the study we carried out on the data. In the search for glutaronitrile in the cold and warm molecular clouds Orion KL, Sgr B2(N) and TMC-1, these rotational parameters were used. These spectral scans were collected by IRAM 30 m at 3 mm. There was no Glutaronitrile identified, and the column densities of the upper limits were established. Sgr B2 and Orion KL total column densities are 1.5 and 5 lower, respectively, than those for the comparable succinonitrile in Orion KL.
