 Title: ANALYSIS OF THE $\nu_{2}$ BAND OF $D_{3}^{+}$ Creators: Foster, Stephen C.; McKellar, A. R. W.; Watson, J. K. G. Issue Date: 1986 Publisher: Ohio State University Abstract: Earlier ion-beam $measurements^{1,2}$ of the $\nu_{2}$ band of the $D_{3}^{+}$ ion have now been supplemented with gas absorption measurements using diode laser sources and a cooled hollow-cathode discharge cell. At least 80 lines have been assigned and fitted using an effective Hamiltonian with a Pade representation of the centrifugal distortion $effects^{3}$. These fits will be compared with others that include vibrationally off-diagonal interactions explicitly. Description: $^{1}$ J. -T. Shy, J. W. Parley, W. E. Lamb, Jr., and W. H. Wing, Phys. Rev.
