The spectrum of a substance — how it interacts with light — provides fundamental insight into its composition. A large number of molecules is typically required to obtain a detectable light-absorption ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

The organic solar cell (OSC) heterojunction interface is where key photophysical processes such as charge separation and recombination occur. The molecular orientation at the interface is one of the ...

What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

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, ...

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...

Each atom and molecule emits a unique spectral fingerprint, characterized by specific wavelengths of light extending across the electromagnetic spectrum, enabling their identification. These distinct ...
