New spectroscopic method for aqueous solutions:Raman pi-function dispersion for NaClO_4 in water

摘要

The dispersion of the H-bond enthalpy was recently determined for liquid water from the temperature dependence of the decoupled OD-stretching Raman intensities I_omega using the relation,H_i= [(partial deriv)ln I_omega/(partial deriv)(1/T)]]_p approx= E_i.See Hare and Sorensen in which a reference intensity I_REF was employed.The maximum enthalpy change is DELTAH_H bond=H_max-H_min,where max and min refer to maxima and minima in the dispersion curve,and omega is the vibrational frequency in cm~(-1).
