abstract :

Ion traps are a well known tool used for studies of ion molecule reactions.
Amongst main advantages over other common methods are sensitivity and the fact,
that conditions at which the reactions are taking place can be very well defined.
Examples of anion molecule reactions of H-, D-, O- with H/H2 and D2 will be
presented.
Ion traps are also used in spectroscopy, where an action spectroscopy scheme has
to be applied. More recently schemes providing access even to pure rotational
transitions, i.e. very low photon energies, has been developed. These schemes
will be demonstrated on spectroscopy of ions of astrophysical interest
(e.g. H3+, CD2H+).
