## Principle of Nuclear Magnetic Resonance (NMR)
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique used to determine the molecular structure of organic compounds. It is based on the magnetic properties of certain atomic nuclei.
### 1. Nuclear Spin and Magnetic Moment
Nuclei with an odd atomic number or odd mass number (such as ^1\text{H}, ^{13}\text{C}, ^{19}\text{F}) possess a quantum mechanical property called **spin**. This spinning charge generates a tiny magnetic field, giving the nucleus a **magnetic moment** (\mu), akin to a miniature bar magnet.
### 2. Alignment in an External Magnetic Field
In the absence of an external magnetic field, these nuclear magnetic moments are randomly oriented. However, when placed... Continue reading "Coh3 chemical name" »

Investing in Mutual Funds

Regular Plans vs. Direct Plans

As in any retail business, the Asset Management Company (AMC) also appoints distributors who act as intermediaries between the AMC and the retail investors. As an incentive to garner funds for their schemes, AMCs usually pay their mutual fund distributors a commission and reimburse distribution expenses.

Lumpsum vs. SIP vs. STP

If an investor has a consolidated amount—for example, a Diwali bonus or savings accumulated over a period of time—and now wants to invest in mutual funds in one go, such an investment is called a Lumpsum investment.

Time Value of Money and Interest Formulas

Time Value of Money (TVM): Money received sooner is more valuable than money received later because of the returns you can earn by investing it.

Compound Interest Formulas

• Standard Compounding: FV = PV(1+k)ⁿ (Use if asked to compound for any period > 1 day).
• Continuous Compounding: FV = PV x e^{APR x t} (Use if compounding is continuous, < 1 day, where t = years).

In these formulas, k = APR/m and n = t x m. The Future Value Interest Factor is (1+k)ⁿ, while the Present Value factor is its inverse.

The Annual Percentage Rate (APR) is also known as the Quoted Rate or Nominal Interest Rate. It should not be used directly for TVM; it must be converted to an Effective Rate based on the compounding frequency... Continue reading "Financial Valuation Principles and Market Regulations" »
