Bandas Vibracionales.
The optic properties of an electrolytic solution were studied. This solution simulates the sanguineous extracellular medium (SME)
using both attenuated total re_x001D_ectance (FTIR ATR) and Raman scattering techniques. Water vibrational spectrum and electrolytic solution vibrational spectrum were compared in the 2700-4000 cm −1 region
where the OH-bond stretching bands are found. In order to prepare the electrolytic solution
three low concentrated salts were used: sodium chloride (N aCl)
potassium chloride (KCl) and calcium chloride (CaCl2). As a result of the low salt concentration employed
there was no found signi_x001C_cant spectrum changes. Because of this
it was necessary to study the e_x001B_ect of each salt
using aqueous solutions with higher concentrations than in the extracellular medium. Results show shifts on the intensity peaks as the concentration increase: from 3286 cm-1 to 3492 cm-1 with IR and from 3207 cm−1 to 3432 cm−1 in the case of Raman. The e_x001B_ect in FTIR ATR is more evident on the asymmetric stretching band
showing a peak in 3492 cm−1 . The sodium chloride solution showed a 58 cm−1 _x0015_shift at low frequencies; while potassium chloride and calcium chloride solutions exhibited lower shifts 44 cm−1 and 39 cm−1 respectively. The strongest e_x001B_ect
using Raman spectroscopy
was found in the symmetric stretching band
where the calcium chloride solution showed the largest shift toward 27 cm−1 frequencies
followed by the sodium chloride and potassium chloride solutions
which exhibited 21 cm−1 and 14 cm−1 shifts
respectively.

Se realizó el estudio de propiedades ópticas de una solución electrolítica que simula el medio extracelular sanguíneo (SME), empleando las técnicas de re_x001D_ectancia total atenuada FTIR ATR y dispersión Raman. Se comparó el espectro vibracional del agua con el de la solución electrolítica en la región comprendida entre 2700 - 4000 cm−1 , donde se encuentran las bandas de estiramiento del enlace O-H del agua. Como consecuencia de las bajas concentraciones de las sales de cloruro de sodio ( N aCl ), potasio ( KCl ) y calcio ( CaCl2 ) que se emplearon en la preparación de la solución electrolítica, no se observaron cambios signi_x001C_cativos en los espectros, por lo anterior, fue necesario estudiar el efecto de cada una de las sales utilizando soluciones acuosas con mayores concentraciones que el medio extracelular. Los resultados evidencian desplazamientos de los picos de intensidad de cada una de las bandas del agua, 3286 cm−1 y 3492 cm−1 para IR y 3207 cm−1 y 3432 cm−1 para Raman, con el aumento en la concentración. El efecto en FTIR ATR es más notorio sobre la banda de estiramiento antisimétrico con pico en 3492 cm−1 . Para la solución acuosa de cloruro de calcio se observó un corrimiento de 58 cm−1 a frecuencias más bajas, mientras que para las soluciones acuosas de cloruro de potasio y sodio se observaron corrimientos menores 44 cm−1 y 39 cm−1 respectivamente. En espectroscopia Raman se registró el efecto más fuerte en la banda de estiramiento simétrico donde el mayor desplazamiento se observó para la solución acuosa de CaCl2 con un corrimiento hacia frecuencias más altas de 27 cm−1 , seguido por soluciones acuosas de cloruro de sodio y calcio con 21 cm−1 y 14 cm−1 respectivamente. |
