We analyse the nuclear stellar population and emission-line spectrum in the range λλ 3100–9700 Å of the infrared luminous merger galaxy NGC 6240. Two spectral extractions from CCD frames are studied: one corresponding to the double nucleus and the other from a light peak 4 arcsec east of the nucleus. The double nucleus is ΔE(B – V) ≈ 0.30 mag more reddened and has a stronger interstellar Na i D ab...
