We report the rotational and vibrational investigation of phenylpropiolonitrile (3-phenyl-2-propynenitrile, C6H5C3N), a ring-chain derivatives of interstellar benzonitrile (C6H5CN).
We investigated the continuum absorption of water vapour diluted in nitrogen, oxygen and air in the range of the pure rotational band of the water molecule (50-500 cm-1). Spectra recordings were performed at room temperature with a Fourier transform …
The high resolution vibrational spectrum of ethyl cyanide (C2H5CN) has been investigated in the far-IR using synchrotron-based Fourier transform spectroscopy enabling the spectral assignment of the four lowest fundamental vibrations.
We report the laboratory far-infrared investigation of aminoacetonitrile ro-vibrational spectrum and the interstellar detection of the molecule in its $v_{11} = 1$ and $v_{18} = 1$ vibrational states toward Sgr B2(N1), in addition to emission from its vibrational ground state
The rotational spectrum of water vapour highly enriched in 180 has been studied by high resolution (approximate to 0.001 cm-1) Fourier transform spectroscopy at the AILES beam line of the SOLEIL synchrotron. The room temperature absorption spectrum …
We present new measurements and analysis of the water absorption spectra in the region of the rotational band, between 70 and 700 cm-1. The higher pressures of the recordings (up to 16 mbar) as compared to our previous measurements allowed us to …
For the first time the $\nu_4$ NH2 scissors band has been assigned in a high-resolution infrared spectrum. A rotationally resolved spectrum of methylamine was recorded using two infrared spectroscopic techniques. A White-type multi-pass cell device …
We investigated the conformational landscape of four naphthalene-derivative molecules — namely ,1- and 2-hydroxynaphthalene and 1- and 2-naphthaldehyde — by means of rotational and vibrational spectroscopy supported by quantum chemical calculations.
