Testing has shown how harmonic amplitudes in nonlinear spectroscopy with the ACSTM can be interpreted in terms of molecular motions, charging and electronic structure.
The ACSTM is capable of probing the same surface site for days at a time, without drift or contamination, providing data on tunneling conditions over a wide range on the local chemical environment, and on the adsorption site.
To achieve these nano-level chemical and spectroscopic data sets requires that the ACSTM be positioned in an ultra-stable operating environment, one free of low-frequency vibrations.
