On Effective Mass of Charged Clusters in Liquid Media

General difficulties related to experimental determination of charged cluster masses M _i in liquid media are stressed (normally M _i strongly exceed typical masses m ₀ of ambient solvent molecules, M _i ?m ₀). This well-known feature deteriorates the product ω _i τ vital in different resonance phenomena by shifting it to the domain ω _i τ≤1 which is hardly suitable for the experiment. Here ω _i is one of the typical frequencies used to measure the mass M _i in the liquid (e.g., the cyclotron resonance frequency) and τ is the relevant relaxation time. Discussed in the paper are the details of the scenario allowing to extract experimental data on M _i under the conditions ω _i τ≤1 where most usual techniques are very difficult to apply.
