Gas phase holomyoglobin (hMb) ions in charge states 7 to 21 were formed by electrospray ionization in combination with a continuous-flow mixing apparatus. Collision cross section measurements show that the highly charged ions are somewhat unfolded in comparison to low charge states but still retain

✦ Synopsis
Calculations of the structure of HaSG4, the SOa-Ha0 adduct, and the magnitude of the barrier between them, were made with the CNDO/Z method. The results suggest the importance of small cluster formation in the gas phase reaction of SO3 and HaO, and offer an explanation for its observed rapid rate.

## Abstract Collision experiments on NS^−^~x~ (x = 2, 3) clusters are reported. Evidence is presented for the gas‐phase existence of the corresponding NS^.^~x~ and NS^+^~x~ species. For x = 3, the mass spectra are very much in keeping with a connectivity SS‐NS (5) for all three charge states. For x
A theoretical study on the stability of the salt bridges in the gas phase, in solution, and in the interior of proteins is presented. The study is mainly focused on the interaction between acetate and methylguanidinium ions, which were used as model compounds for the salt bridge between Asp (Glu) an
