Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes within a sample. Raman spectroscopy is commonly used to identify and quantitate the molecules within a chemical sample. The technique involves shining a laser on a sample and detecting and analyzing the scattered light. The advantages to this type of spectroscopy are its high chemical specificity, sampling versatility, relatively low maintenance, minimal sample preparation, fast and simple routine analysis, and the ability to transfer methods from instrument to instrument in a simple way.
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.
