Time-resolved FTIR spectroscopy (TRS) is widely used to characterize the kinetics of single shot chemical reactions via rapid-scan or repeatable kinetics via the step-scan technique. For a certain class of repeatable experiments, interleaved FT-IR spectroscopy can be a powerful and easy-to-use alternative with clear advantages regarding signal-to-noise ratio and/or measurement duration. No other FT-IR manufacturer offers this capability.Hi
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
