摘 要
在NO2的存在時，以193nm雷射光照射光解氬間質中的HBr 1小時後，分別得到由H原子和Br原子與NO2反應產生之cis-HONO（3411.0，1632.9，1265.8，850.3，638.3及608.7cm-1）、trans-HONO（1688.0，800.3及548.2cm-1）與trans-BrONO（3412.7，1723.4，835.9及587.6cm-1）。若再繼續以308nm雷射光照射間質30分鐘後，其中trans-BrONO會再光異構化為BrNO2（1659.7，1291.0，1196.0及782.7cm-1）。

Abstract
HBr was photolyzed with laser at 308 nm in the presence of NO2, the IR absorption lines were attributed to cis-HONO (at 3411.0, 1632.9, 1265.8, 850.3, 638.3 and 608.7 cm-1), trans-HONO (at 1688.0, 800.3 and 548.2 cm-1) and trans-BrONO (3412.7, 1723.4, 835.9 and 587.6 cm-1) formed by the reaction of H atoms and Br atoms with NO2 in solid argon. The photoisomerization of trans-BrONO to BrNO2 (at 1659.7, 1291.0, 1196.0 and 782.7 cm-1) could occur after further irradiation with laser at 308 nm.
