Ultrafast-broadband scattering SNOM spectroscopy probing molecular vibrational information. Laser interferogram of Polytetrafluoroethylene (PTFE) shows coherent molecular vibration in the form of free-induction decay in time domain (top). The highlighted feature in sample interferogram is due to the beating of symmetric and antisymmetric mode of C-F modes in the resulting the frequency domain (bottom left). Monolayer sensitivity of nano-FTIR is demonstrated on a monolayer pNTP (bottom right). Data courtesy of Prof. Markus Raschke, University of Colorado, Boulder, US

Correlative microscopy with nanoIR and materials property mapping
Complementary IR, s-SNOM, and AFM-IR techniques
Fully featured, high resolution AFM with electrical, mechanical and thermal modes
Correlative microscopy provides new insights into material science
Correlative analysis of spatial map reconstructed from separate correlated AFM and chemical measurements reveal molecular orientation of vacuum-deposited PTCDA
defects. The green population has the a axis of PTCDA parallel to the surface normal, with light blue regions uplifted with the a axis parallel to the surface normal, uplifted
regions with the a axis oriented away from the surface normal (red), and regions with less coverage and a axis oriented away from the surface normal (yellow). The
substrate is dark blue. Science Advances, 2 (10), e1601006 - E. A. Muller, et al.

Complementary AFM-IR and Scattering SNOM images reveal, for the first time, the microscale origins of optical chirality on plasmonics structures. By accessing both the radiative (s-SNOM) and non-radiative (AFM-IR) information on plasmonics structures,
unique and complementary plasmonic properties can be obtained. Khanikaev et al., Nat. Comm. 7, 12045 (‘16). Doi:10.1038/ncomms12045
