The geometrical structures and hydrogen - bond tunneling pathways of the water trimer, tetramer, pentamer, and hexamer systems have recently been characterized with global analysis of potential surfaces, diffusion Monte Carlo calculations, and far - infrared laser vibration - rotation tunneling spectroscopy.

In a new paper published in Physical Review Letters, a team from Carnegie's Geophysical Laboratory examined the structure, bonding and electronic properties of highly compressed hydrogen using intense infrared radiation.
