An unexpectedly high quenching rate (2x10{sup 9} s{sup -1}) of NO(A {sup 2}{Sigma}{sup +}) state has been measured during laser-induced fluorescence measurements of NO densities carried out using a broadband KrF laser in an inductively coupled nonequilibrium air plasma at moderate pressure (38 hPa) and translational temperatures (2500-3000 K). Many assumptions may be made to explain such a high quenching rate but most fail. The quenching species is identified as being produced during the laser pulse but remains unknown in spite of thorough investigations.
