Characterization of Lightpipe Radiation Thermometers for the NIST Test Bed

September 1, 2000

Author(s)

Benjamin K. Tsai, Christopher W. Meyer, Francis J. Lovas

For the past decade, lightpipe radiation theromoeters (LPRTs) have become the sensors of choice in rapid thermal processing (RTP) applications because of their non-intrusiveness and ease of use. In this paper, we discuss the importance of proper LPRT

The Structure of O 3 -CH 4 and the Implications for the O + CH 4 Precursor-Initiated Reaction

August 1, 2000

Author(s)

Angela R. Hight Walker, Gerald T. Fraser, R D. Suenram, Francis J. Lovas

The rotational spectrum of the O 3--CH 4 complex has been measured in a molecular beam using a pulsed-nozzle Fourier-transform microwave spectrometer. An a-type pure-rotation and a c-type rotation-inversion electric-dipole spectrum is observed, complicated
