NORMAL COORDINATE ANALYSES OF THREE-MEMBERED RING MOLECULES.
Chatfield, Dale; Russell, Joel W. ( 1969 )Although complete vibrational assignments have been proposed for many three-membered ring molecules including, in several cases, isotopically substituted systems, attempts to obtain the normal coordinates for such molecules ... -
ANISOTROPIC THERMAL MOTION OF TRIGONAL BIPYRAMIDAL MOLECULES FROM SPECTROSCOPIC DATA.

QUANTUM DEFECTS IN RYDBERG STATES: INTERACTION BETWEEN THE SERIES $s\sigma$ AND $d\sigma$ IN NO.
Jungen, Ch. ( 1969 )In a Rydberg state of a very light diatomic molecule, like $H_{2}$ or $H e_{2}$, the Rydberg electron is characterized by a nearly integral value, l, of the orbital angular momentum quantum number. Rydberg series can ... -
THE $^{3}\Pi_{i} - X ^{3}\Sigma^{-}$ ELECTRONIC TRANSITIONS OF $OH^{+}$ AND $OD^{+}$
Merer, A. J.; Horani, M.; Rostas, J. ( 1969 )Analysis of new high resolution photographs of the $A^{3}\Pi_{i} - X ^{3}\Sigma^{-}$ systems of $OH^{+}$ and $OD^{+}$ (in the region $3000-4500{\AA}$) has led to a more complete understanding of the rotational structures ... -
ANALYSIS OF THE ROTATIONAL SPECTRUM OF METHANOL IN THE REGION FROM $550 CM^{-1}$ TO 900 $CM^{-1}$.
Kwan, Y. Y.; Dennison, D. M. ( 1969 )The methanol spectrum from $550 cm^{-1}$ to $900 cm^{-1}$ (reported in the preceeding paper by D. R. Woods and C. W. Peters) arises principally from b-type transitions between the torsion-rotation levels of the molecule. ... -
THE INFRARED ABSORPTION SPECTRA OF NITROGEN DIOXIDE.
Hurlock, S. C.; Rao, K. Narahari; Jones, L. H.; Potter, R. M.

THE EFFECT OF TEMPERATURE ON VIBRATIONAL BAND CONTOURS.
Murphy, W. F.; Holzer, W.; Bernstein, H. J. ( 1969 )Molecules possessing heavy atoms usually have low vibrational frequencies. Observed vibrational bands will thus have large intensity contributions from transitions originating in excited vibrational levels. Indeed, most ... -
