A millimeter-wave intracavity OROTRON spectrometer in combination with a pulsed supersonic pin-hole jet expansion has been used to record a new subband of the CO-N-2 weakly bound van der Waals complex in the 100-150 GHz region. Seven lines were assigned to the K = 0-0, (j(CO), j(N2)) = (2, 0)-(1, 0) hot band transitions to a thus far unobserved K = 0 state at 9.336 cm(-1) above the ground state. This is the highest in energy van der Waals mode detected so far, and this mode may be interpreted as a doubly excited bending vibration of the CO-orthoN(2) nuclear spin isomer. Hyperfine structure caused by two N-14 nuclei was partly resolved for the measured lines, and the quadrupole coupling constant, associated with the N-2 subunit, together with rotational and centrifugal distortion parameters were precisely determined for the new K = 0, (j(CO), jN(2)) = (2, 0) state. The high lying energy levels of this state provided a sensitive test for the recent ab initio potential energy surfaces. (C) 2019 Elsevier Inc. All rights reserved.
