An alternative approach to these measurements is Near Infrared spectroscopy (NIR), which offers a faster and more environmentally friendly solution. NIR spectroscopy can effectively measure key jet ...

Laser Raman spectroscopy parameters of pure organic matter (e.g., vitrinite, solid bitumen) in sedimentary rocks have been widely applied for maturity determination, but there is a lack of relevant ...

For exploring the nanoscale far beyond the optical resolution limit, tip-enhanced Raman spectroscopy (TERS) is widely recognized as an essential yet still emergent technique. Using this marker-free ...

The estimation of parameters in a continuous time Gaussian stationary process with zero mean and rational spectral density is achieved by an adaptation of the maximum likelihood method. It consists of ...

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

On the other hand, to understand the fine details of how THz interacts with matter, capturing what happens very close to the device’s surface—the “near-field phenomena”—is essential. Existing THz ...
