Molecular Collisions Now Imaged Better Than Ever

Molecular physicists from Radboud University Nijmegen have produced images of the changes in direction of colliding nitrogen monoxide molecules (NO) with unprecedented sharpness. 

By combining a Stark decelerator with advanced imaging techniques, they were able to obtain very high resolution images of the collision processes. 

The results were published in Nature Chemistry on 9 February.

The top images show the research results of Van de Meerakker and his colleagues; the bottom images show the visualised theoretical predictions of the collisions. Red indicates a high probability of change of direction; blue indicates a low probability. The small peaks show the diffraction oscillations (Credits: Image Courtesy of Nature Chemistry).

Message from Bhagavath Geetha
  • Do not get over excited over happiness and do not get over depressed over sorrow.
  • Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.
  • Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.

  • Perform your duty, responsibility and accept the privileges eligible for you.
  • First change ourselves and then try to change others.
  • We are all instruments /tools in the hands of the nature for performing the duty. So do not think that I am doing the duty. Think that I am an instrument to do the duty.
