✦ Synopsis

Rate coefficients for nitrate radical gas-phase reactions with prop-2-en-1-01 (allyl alcohol), but-I -en-3-ol, and 2-methylbut-3-en-2-01 have been determined. Both absolute (fast flow discharge with diode laser detection of NO,) and relative (batch reactor and FTIR spectroscopy) rate techniques were used to measure the rate coefficients The rate coefficients at 294 K are.

The atmospheric importance of unsaturated alcohols and structure-reactivity considerations are also discussed 0 1996 john Wiley t Sons. Inc
