Welcome to the exiting world of NMR... though a little hard to learn... remember... .Why just NMR... .How a ID NMR spectrum look like... .What we can obtain from it... and what can we do for a big molecule

Exercises 1. What is the wavelength of a neutron traveling at a speed of 3. 90 km s- Neutrons btained from a nuclear pile

Characteristic of Superconductors Applications Important Superconductors What Is a Superconductor? A superconductor is an element, inter￾metallic alloy, or compound that will conduct electricity without resistance below a certain temperature

Consumers make choices over bundles of goods. Consumer theory models the way in which these choices are made. A good is simply a product — such as apples or bananas. A good may be specified in terms of time — such as

What is nmr? g NMR, Nuclear Magnetic Resonance, is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static magnetic field and exposed to a second oscillating magnetic field

This lecture presents the two main contributions of \interactive epistemology\ to the the- ory of normal-form games: a characterization of Nash equilibrium beliefs, and a full (i.e. behavioral)characterization of rationalizability. A review of the basic definitions For your convenience, summarize the essential definitions pertaining to models of interactive

第二章3线性方程组的理论课题 3.1.1齐次线性方程组的基础解系 对于齐次线性方程组 ax1+a12x2+…+anxn=0 Ja12x1+a22x2++ =0, ……… amx+am2x2+…+=0 令 (a1)(a1 a22 a1= a2,a2= ,…,an= am2/ amn 则上述方程组即为

第四章向量组的线性相关性 4.1向量及其运算 1.向量:n个数a1,a2,an构成的有序数组,记作a=(a1,a2,an), 称为n维行向量 a称为向量a的第i个分量 a;∈R称a为实向量(下面主要讨论实向量) a∈C称a为复向量 零向量:θ=(0,0,…,0) 负向量:(-a)=(-a1,-a2,…,-an) 2.线性运算:a=(a1,a2,,an),B=(b1,b2,bn) 相等:若a1=b(i=1,2,,n),称a=B. 加法:a+B=(a1+b1,a2+b2,,an+bn) 数乘:ka=(ka1,ka2,,kan)

在R3中,给定四个共面向量a1,a2,3,4,它们显然是线性相关的,但它们中存在两个线性无关的向量,而任一个向量都可由这两个线性无关的向量线性表示(例如:a1,a2线性无关,a3,a4可 ,3,4 由a1,a2线性表示).此外它们中任意三个向量是线性相关的,即它们中任一个线性无关的部 分组最多只含2个向量,数2就叫作这个向量组 的秩
