Infrared and THz spectroscopy of nanostructured dielectrics [PDF]
Processing and Application of Ceramics, 2009 Results achieved using the infrared/THz spectroscopy of various inhomogeneous dielectrics in the Department of Dielectrics, Institute of Physics, Prague, during the last decade are briefly reviewed. The discussion concerns high-permittivity ceramics with

Symbiotic Miras vs. Planetary Nebulae in the Near Infrared [PDF]
ASP Conf.Ser. 303 (2003) 446, 2002 While symbiotic Miras and planetary nebulae are hard to distinguish by optical spectroscopy, their near infrared colors differ. We propose the near infrared two-color diagram to be an excellent tool to easily distinguish these two classes of objects.

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation
Advanced Functional Materials, EarlyView.A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.

Ultrafast infrared spectroscopy with single molecular ions
New Journal of Physics, 2019 We propose a method to investigate the vibrational dynamics of single polyatomic molecular ions confined in a Paul trap. Quantum logic techniques are employed to detect the recoil of single photon absorption events on the molecule via a co-trapped atomic

Measurement Uncertainty in Infrared Spectroscopy with Entangled Photon Pairs [PDF]
arXivSpectroscopy with entanglement has shown great potential to break limitations of traditional spectroscopic measurements, yet the role of entanglement in spectroscopic multi-parameter joint measurement, particularly in the infrared optical range, remains elusive. Here, we find an uncertain relation that constrains the precision of infrared spectroscopic

Infrared electric-field sampled frequency comb spectroscopy [PDF]
arXiv, 2018 Molecular spectroscopy in the mid-infrared portion of the electromagnetic spectrum (3--25 um) has been a cornerstone interdisciplinary analytical technique widely adapted across the biological, chemical, and physical sciences. Applications range from understanding mesoscale trends in climate science via atmospheric monitoring to microscopic ...

Fourier Transform Infrared Spectroscopy of “Bisphenol A”
Journal of Spectroscopy, 2016 FTIR (400–4000 cm−1) spectra of “Bisphenol A” are presented. Absorption peaks (400–4000 cm−1) are assigned on the basis of Density Functional Theory (DFT) with configuration as B3LYP 6-311G++ (3df 3pd).
