Abstract
The rotational spectra of two isotopologues of N$_{2}$$\cdots$ICF$_{3}$ have been measured between 7 and 18.5 GHz by chirped-pulse Fourier transform microwave spectroscopy. The rotational constant, {\it{B}}$_{0}$, the centrifugal distortion constants, {\it{D}}$_{\it{J}}$ and {\it{D}}$_{\it{JK}}$, and the nuclear quadrupole coupling constant of $^{127}$I are precisely determined for isotopologues containing $^{14}$N$_{2}$ and $^{15}$N$_{2}$ respectively. The complex is a symmetric top and contains a linear arrangement of C, I, N(1) and N(2) atoms. The length of the halogen bond between N(1) and I will be presented. Experiments which exploit a Balle-Flygare FTMW spectrometer are currently in progress to determine the nuclear quadrupole coupling constants of the $^{14}$N nuclei.
