Comments: Infrared absorption cross sections of HFOC-134, HFOC-356mff, and HFOC-125 (CHF2-O-CF3) were measured at T = 295 K 
from 500 to 1600 cm-1 and the global warming potentials of the three compounds were estimated. Ultraviolet absorption spectra of the 
ethers were measured between 160 and 220 nm.
