Parahydrogen is required to study the rotational line of molecular hydrogen. We produce parahydrogen by liquefying hydrogen at 20 K on a paramagnetic salt that acts as a catalyst to convert orthohydrogen into parahydrogen. 

The conversion process takes less than 12 hours for an efficiency of 98% conversion. 

If your experiment requires the use of parahydrogen, contact the instrument scientists.
