Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

In a previous article, I introduced the addition of an IR spectrum prediction feature to "Chemliora," a tool for drawing chemical structural formulas in a browser.Predict IR spectra from drawn ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

Sketch of an SX-STM setup. The setup involves using an STM tip to measure a tunneling current (red beam) induced by the illumination of a sample with x rays (blue beam). Sketch of an SX-STM setup. The ...

Even if absorption is visible in an asteroid's spectrum, the shape does not necessarily represent the intrinsic properties of ...

A new spectroscopy method outperforms its rivals by pairing an ordinary frequency comb with an entangled one. From atomic clocks to environmental sensors, many technologies rely on light sources ...
