Interpretation Introduction

Interpretation:

To calculate the specific rotation of given molecules.

Concept Introduction:

Specific rotation: The observed rotation of optically active molecule such as non-superimposable molecule measured using the polarimeter, depends on the experimental conditions and therefore is not a characteristic property of compound.

The specific rotation can be calculated by using the formula given below.

Specific rotation=[α] λT=αc×l

alpha (α) represents the observed rotation measured with a polarimeter. l represents the length of the sample tube. C is the concentration of a solution of a pure sample.λ is the wave length of the light.

To identify: Solving the observed rotation of given molecule.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
