## Description

 Title: The rotational spectrum of the urea···isocyanic acid complex Author(s): Mullaney, John C. Contributor(s): Golding, Bernard T.; Lewis-Borrell, Luke; Legon, Anthony; Walker, Nick; Medcraft, Chris Subject(s): Chirped pulse Abstract: A dimer of urea and isocyanic acid has been generated and observed in the gas phase. The complex was generated by laser vaporisation of a rod target containing urea and copper in a 1:1 ratio, then cooled in a supersonic expansion. Six isotopologues of the complex have been characterised using a chirped pulse Fourier-transform microwave spectrometer in the frequency range 6.5-18.5 GHz. The spectra have been fitted to the Hamiltonian for an asymmetric rotor using PGOPHER. Data obtained from the $^{13}$C and $^{15}$N isotopologues confirms that all nitrogen atoms are close to the a intertial axis while the carbon atoms are not. A tentative structure will be presented.
