abstract = "We analyse a set of optical-to-near-infrared long-slit nuclear
spectra of 16 infrared-luminous spiral galaxies. All of the
studied sources present H-2 emission, which reflects the
star-forming nature of our sample, and they clearly display HI
emission lines in the optical. Their continua contain many strong
stellar absorption lines, with the most common features due to Ca
I, Ca II, Fe I, NaI, MgI, in addition to prominent absorption
bands of TiO, VO, ZrO, CN, and CO. We report a homogeneous set of
equivalent width (EW) measurements for 45 indices, from optical to
NIR species for the 16 star-forming galaxies as well as for 19
early-type galaxies where we collected the data from the
literature. This selected set of emission and absorption-feature
measurements can be used to test predictions of the forthcoming
generations of stellar population models. We find correlations
among the different absorption features and propose here
correlations between optical and NIR indices, as well as among
different NIR indices, and compare them with model predictions.
Although for the optical absorption features the models
consistently agree with the observations, the NIR indices are much
harder to interpret. For early-type spirals the measurements agree
roughly with the models, while for star-forming objects they fail
to predict the strengths of these indices.",
