  The current report covers the period from the second half of 2011 to late
2014. It is divided into three areas covering rotational, vibrational, and
electronic spectroscopy. A signifcant amount of experimental and theoretical
work has been accomplished over the past three years, leading to the
development and expansion of a number of databases whose links are provided
below. Two notable publications have appeared recently: An issue of The Journal
of Physical Chemistry A in 2013 honoring the many contributions of Takeshi Oka
(J. Phys. Chem. A, 117, pp. 9305-10143); and IAU Symposium 297 on Diffuse
Interstellar Bands. A number of the relevant papers from these volumes are
cited. Related research on collisions, reactions on grain surfaces, and
astrochemistry are not included here.
