Researchers have observed hydrogen and deuterium molecules in tiny spaces called picocavities using advanced spectroscopy. This study reveals unique differences between the molecules due to quantum ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

Hydrogen is considered a key energy source that is becoming increasingly popular in today’s energy-conscious world. It must be in liquid form for both transport and use. At 298 K, molecular hydrogen ...
