An inelastic electron tunneling spectrometer is described which is capable of providing constanthyphen;resolution spectra over the 0 to greater than 16thinsp;000hyphen;cmminus;1range. Constanthyphen;resolution data acquisition is especially beneficial in the case of electronic transitions studied by tunneling spectroscopy. Data acquired asd2V/dI2, (d2V/dI2)/(dV/dI)2, and in constanthyphen;resolution mode are compared. At intermediate and at high bias, either of the two latter datahyphen;acquisition methods is superior to the first. At high bias voltage, constanthyphen;resolution spectra are superior.
