nondestructive determination of tomato fruit quality parameters using raman spectroscopy

tomato is a major fruit, as well as a major food science product. there is a need of determining the quality attributes of this fruit (nondestructively) due to the increasing demand of the in agro-industrially controlled areas. most of the commonly employed techniques are time consuming and involve a considerable degree of manual work. sample preparation, juice making, and laboratory tests ...

Two-dimensional Raman-terahertz spectroscopy of water.

Two-dimensional Raman-terahertz (THz) spectroscopy is presented as a multidimensional spectroscopy directly in the far-IR regime. The method is used to explore the dynamics of the collective intermolecular modes of liquid water at ambient temperatures that emerge from the hydrogen-bond networks water forming. Two-dimensional Raman-THz spectroscopy interrogates these modes twice and as such can ...

Coherent two-dimensional terahertz-terahertz-Raman spectroscopy.

We present 2D terahertz-terahertz-Raman (2D TTR) spectroscopy, the first technique, to our knowledge, to interrogate a liquid with multiple pulses of terahertz (THz) light. This hybrid approach isolates nonlinear signatures in isotropic media, and is sensitive to the coupling and anharmonicity of thermally activated THz modes that play a central role in liquid-phase chemistry. Specifically, by ...
