Probing Three-Body Intermolecular Forces: Near-Infrared Spectroscopy of Ar 2 HF and Ar 2 DF van der Waals Modes

December 1, 1996

Author(s)

J T. Farrell, David Nesbitt

Four intermolecular cibrational states of the weakly bound complexes Ar 2HF and Ar 2DF have been studied via high resolution infrared spectroscopy. The vibrations are accessed as combination bands built on the v=1 HF or DF intramolecular stretch. These van

Representation of Axes for Geometric Fitting

December 1, 1996

Author(s)

Ted Hopp

We review methods for representing geometric axes in three dimensions and discuss why these methods have undesirable properties for geometric fitting applications. We then describe a new representation that seems better suited for use in problems of

J H. Klote, Glenn P. Forney, William D. Davis, Richard W. Bukowski

Rapid activation of fire protection systems in response to a growing fire is one of the important factors required to provide for life safety and property protection. Airflow due to the heating, ventilating and air conditioning (HVAC) system can

J Ye, L -. Ma, John L. Hall

Using our newly-developed frequency modulation technique with a high finesse cavity, we have obtained the saturated signal of the weakly-absorbing gas of C 2HD for the P(5) line of υ 2+3υ 3) overtone band at 1.064 υm. An integrated absoption sensitivity of

The Mobilities of NO + (CH 3 CN)n Cluster Ions (n=0-3) Drifting in helium-Acetonitrile Mixtures

December 1, 1996

Author(s)

J A. de Gouw, L N. Ding, M Krishnamurthy, H S. Lee, E B. Anthony, V M. Bierbaum, S R. Leone

The mobilities of NO+(CH 3CN) n cluster ions (N=0-3) drifting in helium and in mixtures of helium and acetonitrile (CH 3CN) are measured in a flow-drift tube. The mobilities in helium decrease with cluster size (the mobility at zero field, K o (o), is 22.4
