Application Notes: Molecular

This application note describes a correlative Raman–scanning electron microscope (SEM) investigation of a lithium-ion battery cathode before and after hundreds of charge cycles. The technique provides an exceptionally detailed chemical and structural analysis of degradation processes on the nanoscale.

Using an automated FT-IR reflection sampling accessory, the surface of a polymer-coated aluminum film was analyzed. Spectral results were used to investigate chemical uniformity across the sample area.

This application note demonstrates using ATR to examine the changes in surface orientation as a function of the distance from the injection point or gate.

Here, we explore the benefits of using a multiple reflection, variable angle attenuated total reflectance (ATR) instrument to generate the most informative spectral data. c

In this application note, we discuss the implementation of offset phase locking using a digital phasemeter, and characterize the stability of phase locking two lasers.

Infrared reflection-absorption spectroscopy (IRRAS) is a powerful tool for the structural analysis of monolayers at the air/water interface.
