TDLAS Monitoring of Carbon Dioxide with Temperature Compensation in Power Plant Exhausts
Applied Sciences, 2019 Temperature variations of flue gas have an effect on carbon dioxide (CO2) emissions monitoring. This paper demonstrates accurate CO2 concentration measurement using tunable diode laser absorption spectroscopy (TDLAS) with temperature compensation methods.

Electronic Spectroscopy of Isolated DNA Polyanions [PDF]
, 2018 In solution, UV-vis spectroscopy is often used to investigate structural changes in biomolecules (i.e., nucleic acids), owing to changes in the environment of their chromophores (i.e., the nucleobases).

X-ray absorption spectroscopy [PDF]
Photosynthesis Research, 2009 This review gives a brief description of the theory and application of X-ray absorption spectroscopy, both X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS), especially, pertaining to photosynthesis. The advantages and limitations of the methods are discussed.

Loss tolerant quantum absorption measurement
New Journal of Physics, 2020 The quantum statistics of entangled photon pairs promise greater performance for absorption measurements than can be achieved classically. However, the performance of a quantum approach is easily degraded under a loss of photons caused by experimental ...
