Paper Abstract

We measured the high resolution absorption spectroscopy of water vapor between 7599cm-1 and 7615cm-1 by narrow linewidth DFB diode laser and kilometers order long path White cell. We observed the minimum detectable absorption of the 10-26 cm/molecular line strength. The measured line parameters show excellent agreements with the values from HITRAN2000 database. The 7600.133 cm-1 line of water vapor listed in HITRAN2000 database was not observed we think the line is inexistent. Seven new weak lines unlisted in HITRAN2000 database were observed which may belong to the isotope H2180 molecular.
