Measurements were made to determine the density of rubidium dimer vapor in paraffin-coated cells. The number density of dimers and atoms in similar paraffin-coated and uncoated cells was measured by optical spectroscopy. Due to the relatively low melting point of paraffin, a limited temperature range of 43–80 °C was explored, with the lower end corresponding to a dimer density of less than 10 7 cm − 3 . With 1 min integration time, a sensitivity to dimer number density of better than 10 6 cm − 3 was achieved. No significant difference in dimer density between the cells was observed.
