IR Frequency Region: Fingerprint Region
0 Views •
2024
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the C=O, C=N, and C=C occur between 1600–1850 cm−1. The...

Eye movement monitoring (or eye tracking) reveals where in space the eyes linger, when and for how long. Here, we demonstrate how eye tracking can be used to investigate the integrity of memory in multiple participant populations, without requiring verbal, or otherwise explicit, reports.

Source: Laboratory of Dr. Dana Lashley - College of William and Mary Demonstration by: Matt Smith When new bonds are formed in the course of a chemical reaction, it requires that the involved species (atoms or molecules) come in very close proximity and collide into one another. The collisions between these species are more frequent and effective the higher the speed at which these molecules are moving. A widely used rule of thumb, which has its roots in the Arrhenius equation1, states that...

In this video, we demonstrate the dissection of the cornea-bearing anterior segment of the porcine eye. The isolated segment can be used for organ culturing to study the pathophysiology of eye disorders.
FAQs
Local blood flow and autonomic nervous system activity can shift thermal conditions around the eyes, making measurements responsive to physiological state. Changes in circulation may alter heat reaching the periorbital surface, while autonomic regulation links the signal to broader bodily responses. This mechanism makes eye region temperature useful alongside other measures, rather than as a standalone indicator.
Ambient conditions can change recorded eye region temperature independently of neural or emotional state. Heat transfer between the body and surroundings, along with local blood flow, can influence the periorbital surface. Consequently, researchers must treat environmental conditions as potential contributors when interpreting differences, because a measured change may reflect external thermal influence rather than the target physiological process.
Infrared thermography detects infrared radiation from the periorbital surface without requiring contact. This makes it a useful complement to behavioral and physiological measures in neuroscience studies. Its value lies in adding a local thermal signal that can be examined with responses involving stress, emotion, attention, sleep, or thermoregulatory control. It does not replace those other measurements.
Reliable assessment depends on careful calibration and control of environmental conditions. Because the recorded surface temperature responds to both internal state and external heat transfer, measurements should be interpreted in relation to the conditions under which they were obtained. Maintaining this attention to measurement quality helps researchers distinguish physiological variation from changes introduced by the surroundings and improves comparisons across observations.
Eye region temperature can contribute to studies of stress, emotional responses, attention, sleep, and thermoregulatory control. In these settings, researchers can examine whether local thermal changes accompany shifts in behavioral or physiological measures. The signal is therefore most informative as part of a broader experimental design, where thermal observations are interpreted alongside other indicators.
In neuroscience, interpretation requires separating thermal changes associated with internal physiological state from effects of ambient conditions and heat transfer. Pairing the measurement with behavioral and physiological data provides context for evaluating stress, emotion, attention, sleep, or thermoregulatory control. This combined approach supports more cautious conclusions than relying on temperature alone.
