Table 4.

Chemical shift values of the major peak observed from the heads of all rats. Chemical shift values are reported with respect to the xenon gas phase and our water-based reference, calculated from the resonance frequency of water protons. The gas phase in Rats 1 and 4 was split into multiple peaks giving a range of possible chemical shift values.

Subject	Chemical Shift (ppm) Gas-referenced	Chemical Shift (ppm) Water-Referenced
Rat #1	194.6–196.1	198.5
Rat #2	195.7	198.7
Rat #3	195.8	198.7
Rat #4	195.9–196.3	198.8
