High-resolution absorption spectroscopy of water vapor molecule was recorded by narrow linewidth diode laser and a kilometer order White cell, minimum detectable line strength is 10-27 cm-1/(molecule·cm-2. The line strength, the self broadening and N2 broadening coefficients of water vapor molecule in the 7599～7616 cm-1 region were accurately determined. The measured line parameters are compared with HITRAN96 and HITRAN2004 databases, some differences exist. The measured line parameters consist with HITRAN96 database, but there exists large difference with HITRAN2004 database. Seven new lines unlisted in HITRAN96 data base were observed, five of them were confirmed in HITRAN2004 data base. Another two lines listed in HITRAN96 data base were observed, but unlisted in HITRAN2004 data base.
