dc.description.abstractThe strong electronic absorption systems of the B-1 Sigma(+)(u)-X-1 Sigma(+)(g) Lyman and the C-1 Pi(u)-X-1 Sigma(+)(g) Werner bands can be used to probe possible mass-variation effects on a cosmological time scale from spectra observed at high redshift, not only in H-2 but also in the second most abundant hydrogen isotopomer HD. High resolution laboratory determination of the most prominent HD lines at extreme ultraviolet wavelengths is performed at an accuracy of Delta lambda/lambda similar to 5x10(-8), forming a database for comparison with astrophysical data. Sensitivity coefficients K-i=dln lambda(i)/dln mu are determined for HD from quantum ab initio calculations as a function of the proton-electron mass ratio mu. Strategies to deduce possible effects beyond first-order baryon/lepton mass ratio deviations are discussed.en_US
