Further, the methodology was successfully applied to selectively map the nanoscale spatial distribution of PVAC in a PS polymer matrix based on a 603cm-1 absorption line, allowing to study characteristic material chemical heterogeneity and interfaces in the far-IR spectral range. It is worth mentioning that sweeping the laser frequency also allows to measure spectroscopic signatures of materials and other nanostructures with unprecedented spectral coverage, enabling studies of fundamental molecular resonances and quantum states in the long wavelength IR spectral range, which until now was not possible.
