Abstract :
The electronic spectrum of the silver–ammonia 1:1 complex AgNH3 has been observed for the first time. The complex was formed using laser ablation and cooled in a free jet expansion, and its spectrum was observed through resonantly enhanced multiphoton ionization (REMPI). The origin of the ÖX̃ band system of AgNH3 located at 467 nm is red-shifted from the corresponding Ag 5p2P1/2–5s2S transition by 8142 cm−1, indicating a significant stabilization upon electronic excitation. The vibrational frequency of the intermolecular stretching mode in the à state was determined to be 378 cm−1.
