—Initial quantum yields for the formation of all four uracil dimers, anti h, t ( I ); anti h, h ( II ); syn h, h ( III ) and syn h, t ( IV ), have been quantitatively determined in aqueous degassed and air‐saturated solutions as well as in degassed and air‐saturated solutions of micellar sodium dodecyl sulfate (NaLS) and hexadecyltrimethylammonium bromide (CTAB). In aqueous solutions the order of dimer yields is IV > III > II > I . Percentages of dimer III decreases from 18‐9 per cent in water to 2–7 per cent in micellar CTAB and to 6.0 per cent in micellar NaLS, but those for dimers I and II increase in the micellar solutions.
