Abstract

A novel design for a temperature-controlled ICR cell is described for use in black-body infrared radiative dissociation (BIRD) studies of weakly bound systems like water clusters. Due to several improved design features, it provides a very uniform black-body radiation environment, and at the same time maintains efficient pumping for a low collision rate on the order of 10−2 s−1. At the lowest temperatures reached, nominally 89 K cell plate temperature, water evaporation effectively ceases, while intracluster reactions in V+(H2O)n with a small activation energy are still observed. BIRD rate constants for Ag+(H2O)n, n = 4–6, are shown in the temperature range T = 160–320 K. For n = 6, a linear Arrhenius plot with R2 = 0.9943 is obtained without any calibration, confirming the suitability of the cell for quantitative BIRD studies.
