Abstract

Radioactively labeled trace gases have been successfully used to study heterogeneous chemistry of atmospheric relevance. Here we present a new synthesis of gas-phase peroxynitric acid labeled with 13N (H13NO4) to study the interaction of HNO4 with ice and snow surfaces. A yield of about 30% for HNO4 was determined. The main by-products were HNO3 and HNO2. Exposure of an ice packed bed flow tube to these species revealed that the interaction with the surface scale in the order HNO3ߙ>ߙHNO4ߙ=ߙHNO2ߙ>ߙNO2.
