title: Precision interferometer calibration technique for wavelength measurements: iodine wavelengths at 633 nm and H(alpha).
abstract: We describe a precision interferometer calibration technique useful for the measurement of the wavelength of atomic and molecular transitions with megahertz accuracy. Using this technique, the wavenumber of the ith hyperfine component of the (127)I(2) B-X R(73) 5-5 transition, which falls within the Doppler width of the hydrogen Balmer-alpha line, has been determined to be 15233.367390(42) cm(-1).
