Abstract
AbstractIn addition to the hundreds of known visual-wavelength Diffuse Interstellar Bands (DIBs), a number of DIBs in the near-infrared (NIR) are now also known to exist. We present here high-resolution UKIRT echelle spectroscopy of two of the NIR DIBs toward sightlines exhibiting a range of visual extinctions. Variations in the strengths and profile shapes of the bands are considered in the context of known properties of the narrow DIBs at visual wavelengths.
