  abstract = {{T}he {OH} stretching vibrational properties of eight serpentine samples from veins of the {N}ew {C}aledonian ophiolite have been investigated by {F}ourier-transform infrared spectroscopy ({FTIR}) in the mid-infrared and near-infrared ranges and by {R}aman spectroscopy. {T}he samples were selected for their monophasic composition ({L}z: lizardite; {C}tl: chrysotile; and {A}tg: antigorite) making them representative of the three serpentine species. {C}omparison of fundamental and overtone spectra allowed us to interpret most of the observed bands and to propose consistent spectral decomposition in individual components. {T}he {OH} stretching bands related to intrinsic vibrational properties of the minerals are distinguished from those associated with chemical substitutions in octahedral sites (mainly {F}e and {N}i for {M}g substitutions). {O}bservations made on the most symmetric {L}z are consistent with previous interpretations and underline the effect of macroscopic parameters on {OH} stretching bands in the {FTIR} spectra. {T}he major importance of the distribution of {OH} bond lengths in the broadening of the vibrational signals of the less symmetric and more distorted {A}tg is confirmed. {T}he combination of the three spectroscopic methods makes it possible to unravel the occurrence of two different types of interlayer {OH} environments in {C}tl nanotubes. {O}ne corresponds to the features observed at 3684 and 7171 cm(-1) in the fundamental and overtone spectra, respectively, and is similar to the local {OH} environment observed in {L}z. {T}he other corresponds to broader signals observed at 3693 and 7200 cm(-1) in the fundamental and overtone spectra, respectively. {I}t reflects a distribution of {OH} bond lengths likely related to local structural misfits between adjacent layers in the tubular structure of {C}tl.},
