searching molecules

[bhushan]

Hi,
I am trying to look for molecules or materials which show an 
absorbtion or reflectio peak at near 1.5micron wavelength.
Also are there any pairs of chiral molecules with closely 
spaced absorbtion peaks in this wavelength , but which absorb
light of different polarization.
Is there a list or a handbook specifying the spectroscopic properties
of various molecules ?
I am an electrical engineer looking for some material to apply a
sensing technique to.
Hope some of you cna help.
Thyanks a lot
Bye
