Comments: The overall quantum yield for hydroxyl radical formation from irradiation of isopropyl nitrite (i-C3H7ONO) 
between 300 and 425 nm in 1 atm air at 296 ± 2 K is reported. The quantum yield was found to be 0.54 ± 0.07.
Ultraviolet-visible and infrared cross sections of i-C3H7ONO measured at 294 K are also reported.
