Abstract It is pointed out that the translational Lorentz effect which has been neglected in all previous analysis of rotational Zeeman spectra has considerable effects on the overall appearance of the Zeeman multiplets if the rotational transitions show first order Stark effect. This situation occurs for symmetric tops and for E-species transitions of molecules with low barrier internal rotations. Inclusion of the translational Lorentz effect leads to corrections to the published g‖-values of symmetric tops which are far outside the quoted experimental uncertainties. As an example numerical results are given for CH3F and CH3CCH.

Tunneling is a ubiquitous phenomenon. Alpha particle disintegration, the Stark effect, superconductivity in thin films, field-emission, and field-ionization are examples of electron tunneling phenomena. In the scanning tunneling microscope (STM) electron tunneling is used as an imaging modality. STM images of flat surfaces show structure at the atomic level. However, STM images of large biological species deposited onto flat surfaces are disappointing. For example, unstained virus particles imaged in the STM do not resemble their TEM counterparts.It is not clear how an STM image of a biological species is formed. Most biological species are large compared to the nominal electrode separation of ∼ 1nm that is required for electron tunneling. To form an image of a biological species, the tunneling electrodes must be separated by a distance that would normally be too large for a tunneling current to be observed.
