H216O line strengths revisited: ν2 and 2ν2-ν2 at 6 μm

► 1273 H2O intensities were remeasured from 783 to 2378 cm-1. ► Line intensities are compared to other available measurements. ► Experimental and theoretically calculated strengths agree to within 2.5%. ► Further improvements are needed to reach 1% absolute accuracies.
