On 01. Feb. 1994 Prof. D. Gerlich took over the group Gasentladungs- and Ionenphysik. In addition to the traditional studies of discharges (e.g. polymerization, etching) various fundamental laboratory studies have been started. The aim was to understand in detail all kind of plasmas, ranging from technical applications to astrochemistry. Developing innovative ion guides and low and high temperature ion traps and combining them with lasers, molecular beams, sophisticated detectors etc., many unique experimental studies became possible.


Since his mandatory retirement (30.09.2009), Prof. D. Gerlich has been actively engaged in several laboratories in Prague, Basel, Köln and other universities. Using techniques and instruments developed in his laboratory, and pushing them to the limits, many outstanding results have been obtained. For past and present activities see Publications and Invited talks.

IR spectroscopy of cold trapped molecular ions using He-tagging

J. Chin. Chem. Soc. 65 (2018) 637-653


This review summarizes experimental activities to study the structure of molecular ions via He-tagging. The method is based on the attachment of a weakly bond helium atom to a cold ion followed by laser induced predissociation (LIP).

IR spectroscopy of fullerene ions in a cryogenic quadrupole trap

ApJ accepted 24.07.2018


After we identified in 2015 the C60+ ion as a carrier of Diffuse Interstellar Bands (DIB) using in Basel first a cryogenic 22-pole [cam15] and later a w4PT ion trap [cam16], we also recorded IR spectra of multiply charged fullerenes using ISORI.
