Malathy ( 1992 )Room temperature absorption spectra of $^{17}O$-enriched ozone have been recorded around 10 $\mu$m at $0.005 cm^{-1}$ resolution with the Fourier transform spectrometer located in the McMath solar telescope on Kitt Peak. ... -
The $v_{3}$, $2v_{2}$ and $v_{1}$ interacting bands of $^{14}N^{16}O_{2}$.
Perrin, A.; Vasserot, A. M.; Camy-Peyret, C.; Flaud, J.- M.; Goldman, A.; Guelachvili, G. ( 1991 )Up to now, except for isolated $states^{1,2}$, the spin-rotation interaction in $NO_{2}$ has been treated using a perturbation $method^{3}$. In the present work, an extensive analysis of $NO_{2}$ Fourier transform spectra ... -

( 1991 )$COF_{2}$ which has been postulated to be an important intermediate in the decomposition of chlorofluorocarbons in the upper atmosphere has been observed in the stratosphere through the identification of absorption features ... -
THE $v_{t}=1$ STATE OF METHANOL
Pearson, J. C.; Brauer, C. S.; Drouin, Brian J.; Pickett, H. M.; Fisher, Jonathan; Shi, Hongyu; Xu, Li-Hong ( 2007 )Methanol is observed in a wide range of interstellar molecular clouds with the highest abundances in hot cores associated with star formation like where the $v_{t}=1$ state was first observed over 30 years ago. Herschel, ... -
THE $v_{t}=2$ STATE OF METHANOL
Brauer, C. S.; Pearson, J. C.; Drouin, Brian J.; Pickett, H. M.; Xu, Li-Hong; Fisher, Jonathan; Shi, Hongyu ( 2007 )Methanol is nearly ubiquitous in the interstellar medium with peak abundances in hot cores associated with star formation. A number of telescopes beginning operations soon will detect the spectrum of methanol to higher ... -
THE $v_{t}=3$ STATE OF METHANOL
Pearson, J. C.; Drouin, Brian J.; Braakman, Rogier; Blake, Geoffrey A. ( 2006 )The rotational spectrum of methanol is characterized by an asymmetric top overall rotation coupled with an intermediate barrier three fold hindered rotation. The spectrum progresses from a torsionally modified asymmetric ... -
VA Mycorrhizal Colonization and Spore Populations in an Abandoned Agricultural Field after Five Years of Sludge Application
Arnold, P. T.; Kapustka, Lawrence A. ( 1987-09 )The effects of five years of sewage sludge application on vesicular-arbuscular mycorrhizal (VAM) fungi were studied. The commercially produced sludge, Milorganite, has been applied to plots monthly during growing seasons ... -
Vacancy defect and defect cluster energetics in ion-implanted ZnO
Dong, Yufeng; Tuomisto, F.; Svensson, B. G.; Kuznetsov, A. Yu.; Brillson, Leonard J. ( 2010-02-01 )We have used depth-resolved cathodoluminescence, positron annihilation, and surface photovoltage spectroscopies to determine the energy levels of Zn vacancies and vacancy clusters in bulk ZnO crystals. Doppler broadening-measured ... -
