A process for isomerizing olefinically unsaturated alcohols over supported noble metal catalysts with a support based on carbon in an oxygenous atmosphere. Said substitution is a hydrocarbon group which may be linear or branched, provided that it comprises, as the longest chain on carbon atom no. Delaying the sampled P and N data by one of zero, one-half, one, or other multiple of one-half clock cycle is selected to remove any skew and aligns the sampled P and N data between bit streams.
