Abstract

Interference fringes appeared between 6000 and 4095 cm-1 in the infrared spectra of thin water-ice films vapor deposited on an aluminum substrate and probed with grazing-angle Fourier transform infrared reflection-absorption spectroscopy. At grazing incidence the position of the fringe under perpendicularly polarized light (Eσ) is 180° out of phase with the position of the fringe under parallel polarized light (Eπ). This shift in fringe position with polarization offers a convenient way to estimate the thickness (±5%) of water-ice films between 0.5 and 1.4 μm.
