TAURINE

This is an H-NMR of Taurine depicting all peaks.


This is a magnified view of the H-NMR of Taurine. This is a set of two triplet of peaks at 3.38 to 3.42 ppm which corresponds to the “Ha” protons attached to the carbon at the “1” position and at 3.23 to 3.28 ppm which corresponds to the “Hb” protons attached to the carbon at the “2” position. These peaks correspond to the sp3 hybridized hydrogen atoms bonded to the first and second carbon in the compound. There is splitting of the signal in the form of three peaks as the hydrogens are affected by two equavalent adjacent protons present bonded to the first and second carbon; from the N+1 rule, N would then equal 2 for each proton, so N+1, (2+1 = 3), 3 peaks would be observed. The three peaks corresponding to “Ha” deshielded by the electron-withdrawing group SO3H, as well causing a chemical shift to the left. This is so because normally without deshielding an sp3 hydrogen attached to a carbon is around 1.4 ppm. For “Hb” is deshielded by an amine group, which is less electronegative, and therefore less electron withdrawing than the effect seen on “Ha” so it is moved to the left less. The triplet peaks exhibit similar heights because the height of peaks corresponds to the ratio of protons between carbons; since both carbons have two H’s, the ratio is 1:1, so their heights are similar.





This is the C-NMR spectra of Taurine depicting all peaks.


This is a magnified view of the C-NMR of Taurine. It depicts a single peak from 50.1-50.23ppm and corresponding to the first carbon bonded to both the sulfur as well as the second carbon. The reason why the C-NMR would correspond to 50.1-50.23 is because the H-NMR corresponding to the protons attached to Carbon #1 is around 3.4 ppm. Since C-NMR peaks represent 15-20 times the amount of ppm of the protons attached to it, 3.4 x 15 is approximately 51 ppm. (See above explanation for H-NMR peak at 3.4 ppm)



This is a magnified view of the C-NMR of Taurine. There is a single peak at approximately 38.20 ppm, which corresponds to the second carbon bonded to the nitrogen group. The reason why the C-NMR would correspond to 38.2 is because the H-NMR corresponding to the protons attached to Carbon #2 is around 3.2 ppm. Since C-NMR peaks represent approximately 15-20 times the amount of ppm of the protons attached to it, 3.2 x 15 is approximately 48 ppm. (See above explanation for H-NMR peak at 3.2 ppm). Although the peak doesn’t exactly match with the H-NMR prediction, it can be deduced that this C-NMR peak correlates with Carbon #2 because it is the lesser ppm of the two C-NMR peaks.

MT. MC KINLEY, DENALI, ALASKA, USA

Denali

Mountain in Alaska

Denali /dᵻˈnɑːli/ is the highest mountain peak in North America, with a summit elevation of 20,310 feet above sea level. At some 18,000 ft, the base-to-peak rise is the largest of any mountain situated entirely above sea level. Wikipedia

HI EVERYONE. YESTERDAY, WE WERE AT THE GATEWAY ARCH IN
ST. LOUIS, MISSOURI. TODAY WE ARE TAKING A BIG TRIP,
BACK TO ALASKA. I KNOW WE WERE THERE BEFORE BUT
THERE IS MORE TO SEE THERE. THIS TRIP IS GOING
TO TAKE IN ALL KINDS OF SIGHTS.

WE ARE GOING TO START OUT IN A BOAT ON
LAKE WONDER. AS WE TRAVEL ON THE BOAT, WE WILL
SEE ALDER AND WILLOW CARPETED HILLS ALONG WITH SOME SMALLER
PONDS. KEEP YOUR EYES OPEN CAUSE THERE IS A LOT OF
WATERFOWL AND OTHER WILDLIFE AROUND.

SOMETHING THAT WON'T BE HARD TO SEE IS THE STUNNING
VIEW OF MOUNT MCKINLEY AND THE ALASKA RANGE. MT. MCKINLEY
IS THE HIGHEST MOUNTAIN PEAK IN NORTH AMERICA, WITH A
SUMMIT ELEVATION OF 20,320 FEET ABOUT SEA LEVEL. YOU WILL
SEE SNOW ON THE MOUNTAIN TOP AT ANY TIME OF
THE YEAR. THERE ARE FIVE LARGE GLACIERS THAT FLOW OFF
THE SLOPES OF THE MOUNTAIN. LAKE WONDER THAT WE ARE
TRAVELING ON WAS CREATED BY RETREATING GLACIERS. IF ANYONE
IS ENERGENIC, YOU CAN HIKE THE MOUNTAIN.

I HOPE YOU ENJOYED YOUR RIDE ON THE BOAT WITH
THE SPECTACULAR VIEWS OF THE MOUNTAINS AND WILDLIFE...
