Which nuclei can be anaylzed by NMR spectroscopy? (i tired just 1^H and 13^C together)(I also tried all of them but 3^H together)(I don't know which of these can be anazylzed by NMR spectorscopy)

1^H

2^H

3^H

12^C

13^C

NMR-Nuclear Magnetic Resonance spectroscopy which involves transition of a nucleus from one spin state to another
The absorption of electromagnetic radiation during transition happens only in spin-active nuclei
The nuclei having nuclear spin not equal to zero are spin-active, when they placed in a magnetic field the transition occurs
The nuclei with even-even ( even number of protons and even number of neutrons) have a spin I=0,odd-odd all have integral nuclear spin, other than zero and (odd-even or vice-versa) have half odd integral
The nuclei having a nuclear spin (I) not equal to zero can be spin-active. E.g: H¹ ,C¹³.
The nuclei having a nuclear spin (I) equal to zero are not spin active. E.g:C¹² .
Although, nuclear spin plays an inevitable role in NMR, along with it also depends on the natural abundance of the nuclei
H¹(99.98%),H²(0.02%),H³(0.00%),C ¹²(98.89%) But I=0,C¹³(1.11%) I=1/2 are its natural abundance.
Finally, with the account of natural abundance and nuclear spin H¹ ,C¹³ can be analysed by NMR.
H² ,H ³ cannot be analyzed due to their natural abundance and C¹² cannot be analyzed due to spin inactive nature.

In 19F NMR spectroscopy, the F nuclei behave just like protons in 1H NMR spectroscopy in that they have a nuclear spin quantum number of 1/2. How many 19F NMR resonances do you expect for PF5? (Assume a static structure. In other words, the axial and equatorial do NOT rapidly scramble and change positions on the timescale of the NMR experiment.)

1) In H NMR spectroscopy, why is the peak for a vinyl proton, C=C-H, shifted downfield relative to that of an alkane proton, C(sp3)-H? Be sure to use the following terms in your answer: pi-electrons, induced magnetic field, and resonance. 2) In H NMR spectroscopy, why is the peak for a -CH2F group shifted downfield relative to that for a -CH2Br group? Be sure to use the following terms in your answer: electronegative, deshielded, magnetic field, and frequency.

I want to understand how this can be solved in c++. Please send a screenshot also with your code so I can see how it is supposed to be formatted or indented. Instructions: Your program will read in a file of commands. There are three types of commands: Warrior creates a new warrior with the specified name and strength. Battle causes a battle to occur between two warriors. Status lists all warriors, alive or dead, and their strengths. A sample...

C programming problem I have to design an efficient algorithm which solves this problem. Also, it needs to include time and space complexities of this algorithm. There is a matrix (N times N) of integers which rows and columns are sorted in non-decreasing order. A sorted matrix and integer M will be given and we need to find the position(row,column) of M in this matrix. it's okay to report only one position if there are more than one answers. when...
