We thank Dr. K. Ohshimo for his help in equipping our photodissociation spectrometer with the laser vaporization source. This work was supported in part by the Joint Studies Program (2003) of the Institute for Molecular Science and the Grant-in-Aid for Scientific Research (No. 15250015) from the Ministry of Education, Culture, Sports, Science, and Technology of Japan.

N2 - The infrared photodissociation spectra of mass-selected Mg +(NH3)n (n=3-6) are measured and analyzed with the aid of density functional theory calculations. No large frequency reduction is observed for the NH stretches of ammonia, suggesting that either all the ammonia molecules coordinate directly to the Mg+ ion or an additional ammonia in the second shell bridges two ammonias in the first shell through hydrogen bonds. Four or possibly five ammonia molecules are allowed to occupy the first shell, in striking contrast to the closure of the first shell in Mg+(H2O)3.
