Ethyl and methyl esters of commercial rhodamines B, 19, 101 and 110 and propyl and butyl esters of commercial rhodamine B were synthesized and isolated with different counterions (yields 70–98%). The 1H and 13C NMR spectral data for these compounds were fully assigned by a combination of one‐ and two‐dimensional experiments. The Fourier transform IR and UV–visible spectra were also recorded and the
