Near-infrared (NIR) spectroscopy is a powerful analytical method for rapid, non-destructive
and label-free assessment of biological materials. Compared to mid-infrared spectroscopy …

The off‐axis integrated cavity output spectroscopy (OA‐ICOS) represents a suitable solution
in many applications with a simple structure and high sensitivity. The off‐axis configuration …

A computed line list for formaldehyde, H212C16O, applicable to temperatures up to T= 1500
