“…In addition, Chirico et al (2016) showed that the Raman peak at 1043 cm −1 , assigned to the totally symmetric vibration of NO 3 ions, could be clearly measured in ammonium nitrate. Our results have confirmed these previous observations (Irish and Walrafen, 1967;Mabrouk et al, 2013;Chirico et al, 2016).…”

Early Diagnosis and Management of Nitrogen Deficiency in Plants Utilizing Raman Spectroscopy

Nutrient deficiency alters growth and development of crop plants and compromises yield. Real-time non-invasive monitoring of the nutritional status of crops would allow timely applications of fertilizers to optimize for growth and yield at different times of the plant's life cycle. Here, we used Raman spectroscopy to characterize Arabidopsis and two varieties of leafy vegetable crops under nitrogen sufficient and deficient conditions. We showed that the 1046 cm −1 Raman peak serves as a specific signature of nitrogen status in planta, which can be used for early diagnosis of nitrogen deficiency in plants before onset of any visible symptoms. Our research can be applied toward crop management for sustainable and precision agriculture.

“…In general, metal oxides containing the group M= =O have strong absorption at 1100-825 cm −1 ; however, oxides with more than one oxygen atom bound to a single metal atom, -O-M-O-, absorb in the region of 1020-970 cm −1 ; 49,50 this band can be shifted due to the hydrogen bonding effects. 51 The bending vibration of the -Pb-OH group is observed below 1200 cm −1 , but when the OH group forms a bridge, the bending vibration occurs at approximately 950 cm −1 . Because Pb(NO 3 ) 2 was used as a lead source, NO 3 and NO 2 groups are present.…”

Determination of lead ion removal from a flowing electrolyte in the presence of a magnetic field using Raman spectroscopy

The results indicate that the ion concentration can be increased more than 80% in a region where they can be removed. The increment in the ion concentration produced by the deflection due to the magnetic field, together with the use of Raman spectroscopy, allows for a rapid analysis of the removed ions without any previous preparation. The proposed method is a potentially useful method for metal ion separation of interest in the medical physics field.

“…In that objective, many studies have investigated the possibility to use optical methods, and more specifically RS for the detection of pollutants in water media [57,58]. The method described earlier in this chapter, based on the calculation of ratios of pollutant-specific peak and water peak, can then also be applied to water pollutants [59,60].…”

In this chapter, the use of Raman spectroscopy (RS) for studies of aqueous solutions is shown. This technique is mainly used for the characterization of solid samples, but presents numerous features permitting its use for the analysis of aqueous media. Indeed, it possesses all the advantages of optical methods (versatility, rapidity, contact-less nondestructive measurement, etc.), but also offers possibilities for in situ measurements. The Raman spectrum will be influenced by several parameters such as the solution concentration or its temperature-phase. Thus, the analysis of a set of aqueous solutions of different concentrations in a certain temperature range can permit the identification of the specific effect of salt and temperature. A proper analysis based on the follow-up of the specific peak areas or intensities can permit the determination of the salt concentration or the phase transition of the studied solution. The analysis can be focused on the salt direct effect on the spectrum, analysis of the salt signature itself, or on its indirect effect on the water signature. The method for the characterization of aqueous solutions of some salts is presented: elaboration of calibration curves and concentration determination. As an application example, a special attention is devoted to aqueous solutions that are used in the winter maintenance domain (solution of acetates, formates, or chlorides), which are very relevant examples of aqueous solution behavior. A specific analysis set to determine the solution solid-liquid phase transitions is presented as well as the thus-constructed phase diagram.
